Extensions- 30 Apr 2019
What can I say about Steve and his team. Being an ex builder and coming off a not so great experience of a loft extension was cautious in who we chose for our Kitchen extension. I chose SK Builders and their approach to our job was first class and we always had a say in how the job progressed. We had complete trust in Steve and he paid us back in spades. They worked bloody hard in the heat of last summer, always here and slogged their guts out. The work was to an excellent standard and everything was completed, ordered on time. Steve worked around our issues and helped us enormously when it came to the knock through and setting up the kitchen area for us. His team of electricians, carpenters, Paul the plumber and Simon the plasterer were first rate. And all lovely guys. Our job was outstanding and Steve and his team were thoughtful and respectful to our needs. Would easily recommend and have recommended Steve to many people asking who we used. Honestly we could not be happier with the job, which had no major issues at all. It flowed like clockwork. All and all SK Builders should be considered if you are thinking of taking this kind of project, you will not be disappointed with the results.

We’ve had multiple jobs done by Silviya. The first was a small extension and downstairs and partial upstairs refurbishment with new kitchen and 2 bathrooms fitted. This large job was completed within 16 weeks and looks exactly as we hoped. Given the extent of works we moved out for the build. The second was the construction of an outbuilding and garden redesign (patio and astro fitted). Again the results are great. We lived in during this project and I worked from home without disturbance. The latest has been the re-fit of new windows, front door and fixing the front render. Again, the results are very professional and minimal disturbance while the work took place. Will definitely use him and his team again, should we need any more building work and recommend them to others

Tiling- 25 Jul 2025
Shiv builders did the tiling for my bathroom. The quote was easy and done via a WhatsApp video. Price was reasonable. The job turned out to be more challenging than we first thought with uneven walls and floorboards were quite worn however they found solutions easily. The team arrived on time and did an excellent job. Always left the place tidy and very polite and professional. I then had a few additional jobs round the house such as changing door handles and fitting light pendants which they happily accommodated and again did a good job. Will definitely be using them for future work.

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.
