Bathroom Fitting- 27 Sep 2026
John recently installed a new bathroom and kitchen and built an understairs toilet room for us. He also did many smaller jobs including rewiring, plastering, roofing jobs. From beginning to end we were blown away by John's work. He was very fast but also never compromised the quality of the work which was always impeccable. He advised us the whole way about the best quality materials to buy and, when things went wrong (tiles not arriving on time etc), he was really helpful and gave great advice on how to deal with any problems. He was also just such a pleasure to work with! He always ensured that the area was very nice and clean after finishing a task. Would highly recommend John to family and friends (and already have done!) and I'm sure we will have him back in the future. Very reliable and trustworthy builder!

Kitchen Fitting- 1 Jan 2023
I have to say that Tyrone who carried the work out for is very professional and commendable. He was always on time and eager to get the work done. His attention to detail is simply quite impressive. Having completed the work i was rather surprised to learn that he called back the next day only to complete a very small detail that he forgot. A small detail that was not exactly noticeable, thus leaving us with satisfactory results. I’m certainly going to recommend their services to anyone who might require their services. Many thanks 👏👏👍

Decking- 31 May 2024
Firstly they came on time and job was finished on time, I would have given 4 1/2 stars overall. There was a couple of things I would have given 4 1/2 stars for and a mostly I would have given 5 stars. They was always on time every morning and was nice and polite. Overall I'm satisfied and looking forward to completing the rest myself. I had so many nice builders come to look and price the work, it was hard to choose. I am very happy with the outcome of the work.

The project lasted from July 2023 to Feb 2024 and comprised of: 1. Single story rear extension with new kitchen and underfloor heating 2. 75m2 patio 3. Internal reconfiguration including removal / installation of walls, new flooring, plumbing (including new boiler), new door frames, doors and skirting, redecoration, carpentry for cupboards 4. Ventilation of existing roof The team are both friendly and professional with Alin always on hand to manage any questions / situations as they arise. The work is clearly costed and every two weeks a valuation takes place to ensure transparency of work undertaken both in original scope and any extras. The quality of the build was excellent, something the building inspector commented on. Alin was recommended to me based on past work, and I in turn would highly recommend him.

What to ask a Smithfield extension builder before hiring?

Before hiring an extension builder in Smithfield or extension building company in Smithfield, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Smithfield 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 Smithfield 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 Smithfield?

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 Smithfield extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Smithfield 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.
