Bricklaying- 24 Jul 2025
Harvey was very responsive to the requirements of the job and to short notice changes incurred by other works being delayed. His team were brilliant and had the job set-up and executed with minimum fuss or mess. They turned up when they said they would and got it all done really quickly. Really pleased with the results and would highly recommend Harvey and his team.

Plastering- 15 Apr 2024
We hired Dean for plastering and tiling our bathroom. Dean came out to review what was required and provided a break down quote quickly. His prices were fair and we appreciated that he was honest in what could and couldn't be done. Throughout the job he was clear on what times and days he could work and was always on time. He cleaned up after himself and never left a mess. The plastering work completed was done quickly and to a high standard, especially impressive when there was a large hole in the bathroom wall from the plaster blowing. We also hired Dean to complete the tiling of metro tiles for us, again the work was completed to a high standard and we are really pleased with the results. The wall (as with all Portsmouth houses) isn't level or straight! We trusted Dean to be left in the house alone and would definitely hire him again.

Extensions- 1 Sep 2025
Ben, Ian and his team did a brilliant job. They came across a few issues this was due to the building plans they had to work from (architectural designer did a disappearing act). This didn’t faze them at all and kept me informed of how they would solve these concerns. They always arrived on time and constantly consulted with me as to how I wanted things to look. The whole extension consisting of a new kitchen and shower/toilet room couldn’t have turned out out any better. They have since completed a few other jobs one being a seating area (completed just from a picture I showed them) with cupboard storage. Again really pleased with the results. Pictures show during and after

Extensions- 18 Dec 2021
Louis and team completed a front of house single story extension, installing 2 steal beams, making good and transformed our house. The workmanship was to a very high level and he came up with a few ideas which we added to the design. Louis is incredibly tidy and often goes further than any builder I’ve seen to keep the space safe and clean. We love our new space and cannot wait to put it to good use.

Decking- 7 Jun 2020
*****HIGHLY RECOMMENDED***** Firstly, these guys are lovely hardworking honest people who were only interested in making sure we got exactly what we wanted! Their work was nothing short of outstanding and I am absolutely over the moon with my decking. Considering my garden is on a slope I didn't think it would turn out as amazing as it did. But thanks to their skill, we now have a fabulous garden space to enjoy. They used only high quality materials and I have to say they are complete perfectionists. I am happy to be a reference for anyone who is thinking of hiring. 5* service, great price and one happy customer!!! Thank you!!!! Actually can't thank you enough!!!

I had major work completed on the front of my house with new steels being needed. Harry and his team were efficient and kept things as clean as they could given the nature of the job. They were polite and kept me informed of each stage and also spoke to my immediate neighbours. The job was finished on time and a professional clean was completed at the end. I would recommend HWG building services and I will be using them again in the near future

Extensions- 23 Jul 2018
Top Class Job by a Top Class Tradesman We can’t recommend Bob’s services enough! We wanted to choose a local tradesman for our brickwork on our single storey extension. We checked out this website and found his very high recommendations from previous customers. We had obtained 4 quotes prior to the job and Bob’s was not the cheapest nor the most expensive. We found his thoroughness in the quote, his vision going forward and subsequently his work ethic alongside his work colleague Gary, 2nd to none. As a team and individually Bob and Gary were punctual, polite and cheery and tidied up at the end of each day. You couldn’t ask for better from a tradesman and we want to say a huge THANKYOU to these genuinely lovely guys. We are so pleased with the quality of Bob’s work and the subsequent independent tradesmen who are completing the extension have all praised his workmanship, complimenting his work as the best they have come across. This praise speaks volumes and tells us we made a great choice. We have already asked Bob to come back later in the year to create a landscaped patio and garden area with features. This will be the perfect finish for our extension project. We are so glad to have found this quality Tradesman. Don’t hesitate to book him up! Cheers Bob! Dean & Sally

What an amazing man Rhodri is. The job was to replace what originally were external 1970s upvc french doors and side windows with new bespoke internal wooden windows and bi-fold doors, replace old external tiled and internal plastic windowsills with wooden, bringing both up to the same level. Rhodri found a solution for every problem he encountered during this job and I can't express how pleased I am
