Extensions- 22 Dec 2022
Imran is a contractor who is personable and is trying hard, but at the end relies on different teams of builders to carry out the work. His knowledge of building work appears at time limited. In our case, this has often led to poor communication/hand-over, extensive delays and often poor (if not careless) craftsmanship. Very stressful. We now have builders (family business) finalising our project.

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 👏👏👍

Bathroom Fitting- 2 May 2024
I have employed DL Construction to install a new kitchen and bathroom. They are still working in my house but so far their attitude towards their task and helpfulness have been exceptional. I can not comment about the final product yet but I am sure everything would be finished to a high standard. Nothing seems to be a problem for Javi. He always says 'yes please' and I think that is his middle name. I couldn't have asked for better. Well done (so far) Javi and everyone in DL Construction.

A really excellent set up of builders. Peter was great in evaluating the work and what we needed done. Sue was clear in her communication on costs, and then execution of the works by Taras and his team was superb. The extension was built in fantastic time-frame, and the end result is great. The work-ethic of the builders is what really makes them so good. They are on-time every day, and relentless with working hard each day.

What to ask a Penge extension builder before hiring?

Before hiring an extension builder in Penge or extension building company in Penge, 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 Penge?

An extension builder in Penge 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 Penge 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 Penge?

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 Penge 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 Penge 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.
