Extensions- 16 Nov 2019
I was very lucky to find Cornel for my building work. His team were extremely hard working, efficient and respectful and the work was done very quickly and to a high standard. Most estimates for the build time were between 8 and 10 weeks - my work was fully complete in 6 weeks. Building control passed all stages of the work without any issues. He is equally proficient at the plumbing, electrics, flooring, tiling and decorating as the heavy building work, even restoring my garden so that it looked better than it did before the build. I am in a conservation area with close neighbours on all sides and Cornel minimised the disruption as much as possible and made efforts to keep everyone happy. His attitude to overcome problems and make sure that in the end you are a happy client drives his approach to the work. I had 10 builders quote for the job and Cornels quote was very competitive and the final costs were exactly as we had agreed. I had spoken to a number of his previous clients before going ahead and they were all very impressed with his work and had good experiences. It can be a difficult decision to choose a builder if you have no previous experience and given the potential for things to go wrong - but we made the right choice. I wouldn't hesitate in recommending Cornel and his team.

Bathroom Fitting- 1 Sep 2026
Sadly…Still have the bath tap leaking. Flooded the bathroom and kitchen Broke the thermostat for the central heating. Condemned my cent heating and now need a new heater £4,000+ The freeze kit didn’t work and should have used the proper machine instead of a temporary Quickfit kit smh and then many times coming to do the job properly (even got a gas engineer that wanted to charge £150 for a job not done grrr)… £801 charged for a new sink to be installed… yes it’s a old flat (like said in the description). Very disappointed for an expensive job that’s not properly done, even now… can’t be bothered to call him back in case it’s more money. We come to these sites expecting true professional…

Bricklaying- 25 Mar 2018
I instructed the level of the walls and gable to be built up to. The brickwork was covered in hessian and I paid him after he said that it was all done. After he departed, I looked under the hessian and the gable was not built up to apex. One area was not built up where it needed only a couple of courses and the other bricked up wall was left lower than I had stated. I phoned Nick and he sent his brother to finish the job next day. The 2 sides of the gable are still at different angles and the brick work is still lower than I had asked for on the other walls. This was not a big job. Only needed a few courses of brick work to level off as the building has been derelict for a few years. My view was that no one will risk a negative review and that is why I paid him. Unfortunately I was let down at a critical moment as the pitch roof chippy was following the bricklayer on this job. Very sad as he could have been engaged on other brickwork on this building.

Landscaping- 3 Jun 2021
On our first meeting I felt comfortable and was glad of input from Robin. Agreed to a plan and only had to wait a few weeks before work could start. All preparations made to protect my drive before skip arrived. All work carried out in a very professional manner and team were very polite and friendly. Even though weather was against ground works they provided shelter so work could continue. I’ve been very pleased with their approach and can’t fault the outcome. Although met with a couple of delays on garden furniture, (nothing to do with Robin and his team, circumstances outside control)all other aspects of this job have met with my approval. Was apprehensive of having people in but can honestly say there have not been any issues and when the skip was removed within an hour, Robin was back on site to clear and wash down the drive. So looking as good as new. It’s been a pleasure having them on my property and will look at using their services again in the future should the need arise. Nothing too much bother. So my thanks to them all.

HW Carpentry was absolutely amazing. They came out the same day, were personable and very easy to talk to. They even arranged to chat to the damp specialist we were using to make sure they were on the same page (re the cause and solution for the problem). They booked us in a few days later and finished the job in one day. Ricky was always available for any questions we had and we are so happy with their work! We will definitely use HW Carpentry again! Can't recommend them enough!
