Extensions- 13 Nov 2020
Well, I do not usually write reviews, but this time is an exception. So after getting a number of quotations, I decided to go ahead with Fredi. The process was very smooth throughout, Fredi is a great individual and a reliable professional. The plan was to build a rear extension, but working with Fredi, we decided to commission him for the patio, changing all house flooring, kitchen, and two bathrooms. All have been delivered to completion with top-notch results. Most importantly, we have now a new family friend...Fredi the builder!!.. my kids say :)

I wanted a side infill extension, converting a one bed into a 2 bed. The works was undertaken by Coulsdon Builders which took around 8 months. I made several changes throughout the project hence the delay. They were so accommodating and never had an issue and was always happy to cooperate. The cost of build was £120k and we stuck to the budget. I am delighted with the works and am grateful they made my house a home. They were clean and tidy on a building site and always kept me updated on progress. This is one builder that I highly recommend and trust. Great work guys and thank you again!

Restoration & Refurbishment- 25 Sep 2025
We were over the moon with our kitchen once Zihni and his team had finished. We had never used this firm before but we will definitely be using them again for future projects. Zihni is calm, knowledgeable, and went over and beyond in helping us not just complete our kitchen project, but in helping us move into a new home smoothly. We are also really appreciative of the rest of his team, as they were all so serious, professional and perfectionists. Zihni's communication was probably the single reason why the completion of our kitchen was such a success.

Extensions- 8 Nov 2024
After much deliberation, I picked Daron and his crew for our job. From start he was very flexible, honest and accommodating. We quickly understood each other. His crew showed up when agreed and hit the ground running. The shell for our side extension was up in 4 weeks, quicker than expected. Quality of work was really good. As I am now taking over to finish the job, I also really appreciated that both Daron and his guys were more than happy to discuss next steps, or how to do some of the things. Also, if I get stuck I know I will be able to give them a ring and get them booked in to complete some of the items. It was a real pleasure working with them all, and should I have another job come up, I will not hesitate to call them again.

Extensions- 7 Jan 2019
I would definitely recommend LBS Property Services and would definitely use them again. LBS have a highly professional team and are very well organised and managed on site. Raymond has a very collaborative, proactive and honest approach with excellent communication skills and was a pleasure to work with throughout all stages of the project. All works were completed to high standard within the agreed construction programme.

What to ask a Chiswick extension builder before hiring?

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

An extension builder in Chiswick 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 Chiswick 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 Chiswick?

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 Chiswick extension builder’s ability to deliver a result that meets your expectations.

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 Chiswick 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.
