About Us

I cannot praise the company person whodid our house enough. He was punctual, polite, very efficient and the overall result was brilliant. Also reasonable cost too. Thank you.

Very personable young man who turned up when he said he would and did a professional job of cleaning our gutters. He tidied up after himself and charged a very reasonable price. Thanks Ethan!

I recently hired Impact Exterior Cleaning to pressure wash my driveway and patio flags. I'm extremely impressed with the results, especially with such a fair price. Ethan delivered great service and went above and beyond to make sure everything was perfect. I highly recommend him to anyone looking for top-notch exterior cleaning services.

Would highly recommend Richard as an electrician. He fitted a new fuse box for us this week. He's efficient, friendly and trustworthy.

Delighted with our garden it’s given us a fantastic outside living space

Ethan did a fantastic job of cleaning our block paved drive, path and two paved patios. Very professional service from start to finish with great communication. Highly recommended.

Top rated work! Excellent job power washing stained wooden planters. Work carried out with care and precision. Would highly recommend Ethan for any power wash tasks.

What a fantastic installation from CornerStone Electrical. Richard also installed an outside double socket and replaced the strip lights in the garage with LED ones. Brilliant service and I would highly recommend.

George came out to clean my patio and decking, and I couldn't be happier with the results! Highly recommend!

A fantastic and professional service from Richard. He replaced and fitted some new ceiling lights. Very efficient, friendly and extremely reliable. He did a great job and I would highly recommend him.

Ethan was so professional.he arrived on time went through the job with me and promptly started. He took photos of before and after and explained the problem I had. He cleaned my gutters perfectly. I would definitely use him again and would certainly recommend him.

A very professional business, Ethan arrived on time and carried out a fantastic job with the minimum of fuss I highly recommend him.

Ethan was great, on time, pleasant and very professional. Will certainly be using him in the future.

Richard came to fix a socket we had a problem with, would definitely recommend him. Superb service!! Came on the same day as we called!! :)

Ethan did an excellent job for very reasonable money. Someone who definitely takes pride in his work and wasn't trying to rush it. Highly commendable.

Had Richard on two occasions over the last few months - once to carry out a EICR (Electrical Condition Report) and then to undertake the recommendations from this (New consumer unit w/ surge protection). Richard was excellent on both occasions, tidy, friendly and explained everything clearly. Wouldn't hesitate to use again in the future & definitely recommended.

Very impressed with Ethan. Courteous, professional and an excellent job. We will definitely use again. Highly recommended.

We urgently needed an electrician on Wednesday evening at approx. 22:30. All of our plug sockets had ceased working. It was essential for my husband’s medical condition that this issue be rectified ASAP. Not knowing a local electrician, I found Richard on Google, I called him and left a message. I was amazed that he called me back without delay. Over the phone, he helped us to identify the issue. This meant that the medical equipment could immediately work.
The following morning he was in contact with us again, as we had only partially resolved the issue the previous evening. Due to his work commitments, although he tried, he was unable to get to our house; however he told me what to do again over the phone.
After following his instructions, all of the sockets were fully functional. If the same issue ever occurs again I will know what to do.
I cannot thank Richard enough for his immediate response, the customer support and care that he provided. Without the medical equipment my husband cannot function.

I had my gutters and lower roofs cleaned as well as jet washing a large front and rear paved area. I cannot recommend George and Ethan highly enough. Such a friendly and professional service. I’m so pleased!

Richard did a fantastic job of our Hypervolt electric car charger, very tidy job and some great advice on the installation.

Fantastic service and works completed to a high standard. Neighbour was impressed and had their gutters and facias cleaned as well!

Very pleased with the work carried out on my gutters. Ethan was very professional and responded with a quote very quickly. He arranged a mutually convenient slot to carry out the work and arrived precisely on time. So reliable and it’s refreshing to have no hesitation in recommending him for cleaning gutters or I’m sure for all the services he can provide. I will definitely book him again. Thank you.

I called Impact Exterior Cleaning to clear the moss off my 1960s house, its fair to say i did not know my roof tiles were as light a shade as I had thought! George and Ethan did a great job, fast efficient and I was surprised with the results. They covered the floor with a tarp that thankfully caught all the moss etc off the roof and advised its good compost so they put it on the beds. The muck that sprayed from the roof down some of my windows and next door was also quickly cleaned away (including spray on the the neighbours which kept them happy). Overall would recommend and use again

Richard has done a great job. He has fitted 3 outside lights, an outside socket for a hot tub, and some new indoor sockets to make working from home easier! He is very helpful, knowledgeable, reliable and tidied up. I would definitely recommend him.

Ethan of Impact Exterior Cleaning recently cleaned the extensive paving round our house and garden.
He was very friendly and had a thorough and professional approach.
He provided a detailed estimate for the job.
He turned up on the date arranged with all his equipment and did a very thorough job. We're very happy with rhe results.
Good Luck Ethan, you deserve to well.

George and the team did a fantastic job cleaning our roof. Efficient, thorough, responsive and professional. Would highly recommend!

Ethan pressure washed, put down weedkiller and sanded our extensive block pave and also pressure washed a large area of stone slab.
He did an excellent job quickly, cleared up on completion and was extremely accommodating & courteous.
Would have no hesitation in asking him back

Ethan did an amazing job jet washing all the drive and back garden making it safe for the children and myself to walk on. Ethan is very professional, enthusiastic and punctual and I want to say a big thank you 🙏

After &before pictures ..polite Great team and excellent work

We would highly recommend Richard. He replaced 18 of our light switches and at least a dozen sockets including a tv aerial. In addition he fitted 5 pendant lights and an outside double socket. He works conscientiously and to a very high standard. Thank you, Richard.

I recently had the pleasure of using Impact Exterior Cleaning Ltd for my home’s exterior cleaning, and I couldn’t be happier with the experience! From the very first enquiry, their team was incredibly helpful and responsive, guiding me through the process with clear communication. They were punctual and arrived exactly when they said they would, which I really appreciated.

The quality of their work was outstanding, and their high standards were evident throughout the service. They not only cleaned my artificial grass and patio to perfection, but they also took the time to explain the aftercare needed to maintain the results. I highly recommend Impact Exterior Cleaning Ltd to anyone looking for reliable, professional exterior cleaning services. Their commitment to customer satisfaction and attention to detail truly set them apart! Don’t hesitate to reach out for a quote; you won’t be disappointed!

I asked Richard to do quite a lot of small jobs and to replace my main board and label everything up. It was a 2 day job but he did a great job, worked really well and was really thorough, now I have some fancy extra LED lights on top of everything else. Will use again, I'm even thinking about what other projects I can get him to do.

Excellent service from Ethan, reasonable price, on-time, great quality work. Highly recommended.

Ethan was exceptional- thorough, efficient And very courteous- super job, we plan to ask him back to clean the gutters again in January- can't praise him enough

Fast, efficient service for cleaning at height.

George was brilliant from start to finish in terms of his communication and the quality of the job done. We are so happy with the result and would definitely use them again, highly recommend!

Ethan has carried out an excellent job on our roof and areas of render on the house.We are extremely pleased with the result - cannot recommend him too highly!

Ethan arrived promptly, checked if there were any areas of concern and then completed a very thorough and efficient cleaning of all the guttering including extra he hadn’t expected which he didn’t even charge for.
Gutters look like new.
Would highly recommend him and will certainly use him for all future gutter maintenance - thank you

I can't recommend CornerStone enough. They've now done two jobs at my Gran's bungalow and have been brilliant to deal with. From being able to fit in a same day visit to solve a problem to being polite, friendly and proper professionals , they've been top class. Thanks.

Ethan has just completed cleaning my 300sq.m. roof which was covered with lots of moss and he’s done an excellent job and completely cleaned up after the work was done. He is very professional and a very pleasant person to deal with, he deserves the good reputation he has.

After trying a few companies, I have found this to be the most efficient and best value for money. Ethan was very professional, personable, and did a great job. Will be employing their services for the foreseeable future and recommend others to do the same!

IMPACT EXTERIOR CLEANING.
After an extensive online search for a sole trader . Who cleaned gutters, fascia and soffits. I came across Ethan, impressed by the reviews . I made contact with Ethan at lunch time on a Friday . Ethan called me within an hour, and made a visit to give me a quote for the work two hours later. What a breath of fresh air to find such a young man with such an excellent attitude . The quality of the work he carried out was first class . So much so that my neighbour has asked Ethan to carry out work on her property. If you are looking for reliable, punctual and professional company. Then look no further than Ethan, I will definitely be using his company in the future and have no hesitation in recommending him to my family and friends. Well done Ethan.

Brilliant service from Ethan at Impact Exterior Cleaning. Our gutters were overflowing thanks to a blockage, and even during horrible weather he turned up promptly to give us a quote and was here the following day, again during horrible weather to completely clear all our gutters on two buildings. Very polite, lovely guy, great value and impeccable service. Would highly recommend!

Lovely polite young man. Punctual, very tidy, efficient and thorough. Explained everything and showed photographs of before. And after job . Highly recommended 😊

Really friendly man
Came when arranged. Stayed and did the job there and then
Reasonable price and I will most certainly use this company again

Absolutely thrilled with the cleaning service I received yesterday! Ethan was punctual and very professional. I couldn't be happier with the results.

Fantastic job done by Richard today very tidy and time efficient. Working from home wasn't a problem at all and I am very happy with new sockets and disconnection of the unwanted one. 5/5 If you need an electrician definitely would recommend Richard:)

Richard fitted 2 ceiling fans for me today
He also set up the app on my phone so I could use them that way
I found him very professional and a lovely guy to deal with also the price was very reasonable
I’d definitely recommend him and will be using his services again

Very good service and at a reasonable price. Helpful guy and would definitely use again.

Ethan did a fantastic job clearing my gutters. He was polite and prompt at responding to my initial enquiry.

Ethan is a star! He jet washed the drive with such detail, would definitely use again: in fact
I’ve asked him to do the back of the house.
Couldn’t recommend more highly

Ethan replied to my text promptly and kept in touch. He was able to complete the job very quickly. He arrived on time, was very hard working and professional. Easy to talk to and did a thorough job. Highly recommended.

Eithan is highly professional and thorough from start to finish! Pricing was clear, he's polite and worked to a really high standard. I will definitely be using him again!

Excellent gutter cleaning service. Ethan went the extra mile and took a look at some gutter issues at the property. Shared several photos and videos with me after the job was done. Highly recommended.

We were satisfied with the cleaning. Windows, driveway and conservatory exterior cleaning were offered for a competitive price and thankfully Ethan and team accommodated our request on short notice. Would recommend for exterior cleaning services.

Fantastic response and job from George and Ethan. Could not have been more accommodating and my roof drains fully repaired and cleaned on limited noticejustbeforeChristmas. Can highly recommend Nick

Efficient and really nice result

3 Led down lighters fitted in en-suite and 2 pendant lights fitted. Everything is working well and everything left clean and tidy. Very pleased with all work. I will definitely use again, Thank You

Richard responded quickly to a request for a quote. He came out on time and quoted a very fair price.

He turned up to do the work on time, was very helpful and did an excellent job and I can recommend him !!!!

The whole process from start (obtaining quote) to finish was effortless. Richard has a quotation/invoice/job system that ensures you have full communication at all times. We even got reminder texts regarding the visit. On the day of the work Richard arrived with a big smile on his face and literally worked for 5 solid hours with a short break. My house was left immaculate. We are delighted with the work carried out. I would highly recommend Cornerstone. You won’t be disappointed. 🤙😁

Ethan was highly professional. He made an excellent job of cleaning our gutters.He fully explained the issue. Showing photos of before and after. He was also very tidy. I will be recommending him to family and friends. Thank you.

Great job - very efficient and friendly. Talked us through the process and was done so quickly on the day of fitting the Hypervolt charger. Has made charging our car much easier! Would highly recommend them and would definitely use them again. Thanks again Richard! 😊

Ethan cleaned the gutters and downpipes at our property and did a fantastic job. He didn't rush the job or take any shortcuts and was very thorough in his approach. Great communication skills and was very professional and a delight to deal with. Highly recommend him to anyone who wants a hard working, honest individual starting off a new business and was very reasonably priced. Well done Ethan, great job!

Ethan is a lovely man and his work fantastic.Very thorough in cleaning our gutters .Showed us before and after pictures.Will definately have him again

We've used Impact Xternal Cleaning a couple of times now and they have on both occasions done a fantastic job cleaning our windows and balconies. Lovely guys and nothing is too much trouble. Will be using again and would highly recommend!

We have just had our gutters cleaned and part of the drainage/gutter system replaced. We were very happy with the results and service received throughout. They took care in their work and made sure we were happy with everything before they left. They also made sure to replace certain minor issues that were out of order with the existing gutter connections, issues we didn't know about until they were shown to us. Overall very impressed with the company and we will hire them again if needed. Would recommend to others.

We’ve ordered an EV and wanted to get an EV charger fitted whilst the OLEV grant was still available. I consulted the government website list of approved installers and contacted about 6 companies. Only two responded. Cornerstone contacted me straightaway and arranged an early visit. Richard was very helpful, described what the job entailed and examined our electrical system very thoroughly. I initially thought the quote was high but this was because the Hypervolt charger is quite expensive as it has a lot of functionally. I eventually received a second quote from another installer and the quote was almost identical. I went with Cornerstone because I was impressed with Richard’s reliability and his professional and organised approach. The payment schedule was also better. I received reminder text messages prior to installation and the whole operation was very slick. The installation took a morning and the job was very neat and tidy. I received the electrical and building regs certificates promptly following the installation. I haven’t tried the charger yet as we’ve not taken delivery of the EV but I’m thrilled that it appears to work with our solar panels out of the box. There are various settings but I can set it to send excess solar to the car instead of sending it to the grid. Although the amount of gain will be small, on a sunny day I could probably add about 60-80 miles worth of free juice to the car. Given what is likely to happen soon to electricity prices this could come in handy. I’m extremely satisfied with Cornerstone and have no hesitation in recommending them.

Richard came to fit 3 ceiling lights, change some light switches, fitted 2 new smoke alarms and fitted a double outside socket.
Arrived on time, very friendly and cleared up when finished.
Would definitely use again and recommend 100%

Ethan has done an excellent job on our rendering, which needed a few treatments to get it to how it looks now. I would
highly recommend Ethan, for any rendering work, jet washing ( plus other services) to make your home look immaculate Great work!

Personable, reliable and a great job. We used the lads to do our patio, decking, render and fencing for the second year. Highly recommended

Richard recently installed a new induction hob in our kitchen, which necessitated the fitting of a new power circuit and switch. In freezing weather, he installed new trunking round the outside of the house – from the circuit board in the garage to the kitchen – to accommodate the wiring and still managed to keep smiling.

We’re really pleased with the work and highly recommend Richard and Cornerstone.

Excellent job completed by Geroge & Ethan cleaning our fully rendered house. From survey, quote to completing the job , they were both conscientious and also cleaned our side stone path which had a huge build of algae. Highly recommend for any external cleaning needed

Richard came and fitted 5 different light fittings for us. He was professional, tidy and worked to a high standard. We were extremely happy with the work carried out.

Ethan made an excellent job of cleaning our extremely grubby front drive and rear patio area. He arrived on time and carried out a very professional service at a very reasonable price. We would definitely have work carried out by him again.

Richard came to check my electrics plus installed new pendant/light fittings in all rooms, Ring security devices outside as well as a double socket. From start to finish he was punctual and professional. Highly recommend!
