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

Restoration & Refurbishment- 11 Sep 2022
My partner and I couldn't be more thrilled with the service and standard of workmanship that Matt and his team have achieved on our recent first floor conversion. The quality of the finish is fantastic and I would have no hesitation in recommending him to family and friends. Throughout the whole build communication was brilliant and at no point did Matt or Tony ever assume or make any decisions without consultation or checking in. Problems and solutions were worked through jointly and nothing was every to much trouble especially as the scope of what we originally asked for grew as the build went on. This was driven by us adding items to the original brief. They were really helpful with recommending showrooms and suppliers which made the decision making process streamlined. We were lucky to move out for the build but everyday our home was kept clean and tidy. Finally all snagging has been dealt with promptly and it's lovely to see that the company is also striving for a high standard of finish. Thanks very much for everything.

What to ask a Southsea extension builder before hiring?

What qualifications and experience do you have as an extension builder in Southsea?

An extension builder in Southsea should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Southsea extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Southsea?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Southsea extension builder’s ability to deliver a result that meets your expectations.

Do you offer a guarantee for your work? Most Southsea extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
