James helped us to choose fixtures and fittings ( which we were grateful for especially as the recomended shower we chose is AMAZING ) We were extremely impressed with his workmanship and found him and his team to be very professional, reliable and punctual.

Definitely using them to remodel our kitchen.

Excellent service from start to finish. The plumber (Kulhash) arrived on time, completed the job to a very high professional standard, and was friendly and courteous throughout. The price was also very fair and reasonable. I’m really happy with the work and would definitely recommend him to anyone looking for a reliable and professional plumber.

Bricklaying- 24 Jul 2025
I recently hired Louis to build a new fence outside my home, and I couldn’t be more delighted with the results. From the moment he arrived, he was the epitome of professionalism—punctual, polite, and incredibly courteous. The quality of the brickwork is outstanding. Each brick is perfectly placed, the lines are crisp, and the finish is flawless. It’s clear Louis takes great pride in his craft, and his attention to detail is second to none. The fence has genuinely transformed the exterior of my house and added a real touch of elegance. Beyond the technical skills, Louis was a pleasure to have around—well mannered, respectful, and always happy to answer questions. He kept the area tidy, worked diligently, and made sure I was satisfied every step of the way. Highly recommended for anyone looking for top-notch bricklaying with a friendly face and a professional attitude. I’ll definitely be calling on Louis again for future projects!

Can’t speak highly enough of Gary and Ed - they’ve helped me over the last 7 years or so from everything from a whole house renovation (new bathrooms, new ceilings, new floors, new bedrooms, landscaped garden, even installing a catio!) through to ad hoc bits and bobs. They are good at thinking around a job creatively to help find solutions to things, and generally really helpful. They are super trust worthy and great to have around. Always go above and beyond, and very good with my cats!

Works consisted of hip to gable loft conversion under permitted development and a refurbishment of the first floor of a semi-detached house into a four bedroom/bathroom layout, including new windows, balconies, wiring and plumbing as well as sound proofing the walls. With 100m2 of works this was my first introduction to a major building project and I was worried by the horror stories I have heard about builders. From the outset Monika set my mind at rest, listening to what I wanted, making helpful suggestions, offering tips for instance on how to save on the scaffolding and always asking me when choices needed to be made. She took the trouble to ensure that I knew what was happening, with daily photos of progress without the need for me to climb scaffolding. I was working to a tight timescale and budget, which Monika understood, and even having accommodated a number of changes including some additions, the project came in on time and on budget. All of the workers on the site were very professional and the quality of the work and the attention to detail was exceptional. I have no hesitation in recommending Monika and her team - I went into this project apprehensive and not sure what to expect; thanks to Monika, I came out the other side delighted by and looking forward to working with her and her team again to renovate my ground floor.

What to ask a Welling extension builder before hiring?

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

An extension builder in Welling 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 Welling 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 Welling?

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 Welling 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 Welling 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.
