Tiling- 16 Feb 2026
Luis did an excellent job on my bathroom. He had to do a lot of prep work before starting the tiling, including rebuilding the floor and repairing the walls. At every stage he explained what needed to be done, ensured that I wanted to go ahead, listed the materials that would be needed, and the cost. It made a huge different to me that Luis was willing to source and purchase all materials; he checked in with me from the suppliers as to choice and cost, and sent receipts for every penny. I cannot recommend him highly enough, for his knowledge and expertise, his honesty and hard work, and also for being such a lovely person, nothing is too much trouble. I am delighted with my new bathroom, and am planning more home improvements with Luis, when he is free again!

Restoration & Refurbishment- 29 Mar 2018
A pleasure to deal with . Agim and his team worked hard to a very good standard.They often worked later than i would expect so that they were ready to move onto the next stage of the job the following day. Agim was very knowledgeable of all building regulations and was ready to offer me solutions when they were needed. All his team were courteous , polite and also knowledgeable. This was the first time I have used A&B but I would have no hesitation of using them again and recommending them to others.

Extensions- 5 Sep 2019
One of the best builders I have ever worked with. PMB take great pride in the work they do and finish to a exceptional level (even better than a lot of premium and expensive builders in the industry). Colin's knowledge about all aspects of building work is unmatched and that shows in the end product that he and his team delivered for me. PMB did a full refurbishment & substantial extension (everything knocked down except 3 external walls) - ground floor ext, first floor ext, loft extension, full re-wire, plumbing, gas, UFH, walls, plastering, fitting, decorating etc. His prices are reasonable and he advised when unexpected costs come up so I could make a decision on what to do. I will definitely use him again.

James managed our kitchen extension project and took ownership of all carpentry, and we couldn’t have been happier with the outcome. The project was delivered smoothly and to a high standard, and James was a pleasure to have working at our home. We especially loved the outdoor pergola / cinema area and hot tub decking he built too, which was technically quite challenging and looks absolutely fantastic. I would absolutely recommend Linear Carpentry to friends - and have done!

We recently completed a large renovation which included extending our kitchen at the rear of the property, changing levels in the garden and converting our loft with an additional bedroom and en-suite. Ben, Steve and the rest of their team were amazing throughout. We had difficulty moving out of the property as our short term let fell through but the team worked tirelessly to enable us to ‘live in’ whilst much of the build was going on (which I know wasn’t ideal!) I highly recommend Integrated Homes as Ben and Steve were so knowledgeable, considerate and professional in their work.

What to ask a Broxbourne extension builder before hiring?

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

An extension builder in Broxbourne 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 Broxbourne 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 Broxbourne?

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 Broxbourne 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 Broxbourne 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.
