Painting & Decorating- 6 Oct 2022
Very pleased with our choice. We initially got four quotes from different builders, most of them were terrible at communicating apart from Alfred. He was very easy to work with, responsive and very careful with our brand new house. His team was hard working, tidy and fast. They completely renovated our garden from removal of old decking and gravel to setting up new fences, levelling and turfing the ground. They also removed our old kitchen, partition wall and carpet, as well as did jobs like plastering, building a wall and set up lights and shelves. We’ll surely have him back soon to work on other jobs.

Khin and Senh did an amazing job redoing all the skirting in our home. Their quote was competitive and their workmanship outstanding. They helped us source the materials to our specification for a great price, handling all the delivery details and were happy to pick up any bits and bobs to get the job done. Each day they arrived on time and often worked late to accommodate the fact we had carpets coming in the following week. After each day tools and materials were squared away and they would send updates on progress. The final product was top quality and has nicely finished off our home as part of a large book of renovations. Finally any snags that I did notice they were happy to come back and address, I couldn’t have wished for any more from these guys. All the best !

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.

What to ask a Waltham Forest extension builder before hiring?

Before hiring an extension builder in Waltham Forest or extension building company in Waltham Forest, 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 Waltham Forest?

An extension builder in Waltham Forest 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 Waltham Forest 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 Waltham Forest?

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 Waltham Forest 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 Waltham Forest 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.
