Handyman- 14 Jul 2018
Would not recommend. Grouping poor & cracking, tiles not flush causing build up of grime. Cases not fixed properly. Chipped window sill. Flooring starting to move. Didn't want to leave feedback but 2 years on and we are having to have things replaced. Don't want to ask them back as getting them to replace our bath they broke was drama enough. A lot of money spent on this project we'd of never expected to have to touch it for years. Very disappointing

Bricklaying- 13 Jul 2025
Excellent completed work from Walid. Friendly, fast and polite communication with every question I asked, the work was booked in quickly and completed, and Walid even added in additional work when I asked him, with very fair pricing. I highly recommend Walid and have asked him to quote for some new work.

Roofing (Flat)- 15 Apr 2016
An honest builder, came an inspected the roof and advised that not the whole roof needed replacing, only the section that was damaged needs to be replaced (other builders who inspected the roof advised the whole roof would have to be replaced) Quote received within 24 hours and once this was accepted gave me a start date. Email received the day before start date that his team will be on site the next morning. Received photos of the roof before and after, very pleased with the job. I will keep his contact details in my diary, will always approach him first for any building work required in the future.

Stonemasonry- 27 Jun 2025
Our back garden wall gate surround was falling apart and the lintel was splitting so we needed someone to rebuild the surround and set things right. Kyle has been brilliant. He was the only one we contacted that wanted to come and see the job in person to provide a quote. He was clear about what would be required and timescale, his quote was competitive and he was fully transparent about the possible additional costs once the work began as there may have been other issues going unseen underneath. He arrived on the agree date and cracked on. The work took about a week as promised and the finish is perfect, and we are so pleased! Wouldn't hesitate to have him back to do further work and would highly recommend. Thanks Kyle!

Fencing- 21 Aug 2026
I am absolutely delighted with my new garden fence. Webb's construction are amazing. Father and son Jake arrived as planned. They completed the job to an exeptionally high standard. Jake and his dad were so polite and amenable. I felt really confident that I had chosen them to do the work . On completion everything was left spotlessly clean. They took away and disposed of the old fencing for me. I would absolutely choose Web,s construction im the future. I recommend that you do too. Rachel.
