Extensions- 7 Feb 2020
I had installpro put an extension on my kitchen by knocking a lean-to and extending into that space, also completed insulation and roofing on the new extension and existing roof, this involved building new external walls, damp course membranes, plastering, new cast iron radiators were plumbed in, new electrical circuits and sockets, tiling, skirting, painting, new sash window fitted, new guttering and fascia and even a fitted kitchen bench was made from scaffold boards, which came out really nice. Marek was very professional and everything was done in a timely manner, no waiting around once things were agreed on. Always early every morning and working full days, even one of his team worked a Saturday to stay on the timeline. The quality of the work was very good, I was impressed with the roofing, proper insulation was used throughout, at the side of the roof behind the fascia too and new lead flashing was finished properly. The team that worked here were very clean, always using proper dust sheets and cleaning up at the end of each day. At the end of the job, final touch ups were made after consultation, to make sure I was happy with everything and then Marek saw that a proper cleanup happened and everything was completed on time and on budget as outlined at the beginning. I can recommend Installpro, and I will use them again for future work on my property.

Latest review:
My previous builder abandoned the project midway leaving me with trust issues . I was looking for someone who was reliable and experienced and had work ethics as well to complete my side extension at my property and driveway. I also had side storey done as well. My colleague recommended him and I cannot thank him enough . From start to finish his approach towards my project was so professional. He is so passionate and dedicated and that certainly reflected in the project both during and after it was all completed. My trust issues were finally restored as well as I noted how much time he took to ensure that everything was completed to the highest standards.I would highly recommend his services .

What to ask a Hackney extension builder before hiring?

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

An extension builder in Hackney 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 Hackney 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 Hackney?

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 Hackney 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 Hackney 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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
