Scott is punctual, very polite, knows his job really well. He came promptly after a courtesy call and completed the job to the fullest satisfaction. He made sure we are happy with the outcome and very friendly. I would highly recommend Scott for TV mounting, any unit assembly from flat box packing, fixing and installation and brick works. He knows everything and has loads of experience in this field. I will definitely use him again. Thanks Scott!!

Extensions- 30 Jul 2019
Nathan from HCJ Building Service was excellent in all respects. He built an extension to our garage, which involved block-work, timber framing, roofing, cladding and installation of a door. When he visited the site to provide an estimate, he was enthusiastic and knowledgeable. His quote was competitive and he promptly answered a few questions we had about some of the technical details. When working on the project, he always arrived when he said he would and left the site tidy when he finished. My wife and I were impressed with how hard he worked, barely stopping to drink a coffee. When we interrupted him to find out how things were going he was happy to give us an update. He was always friendly and polite. He completed the project on time and left the site as he found it, removing all his waste. The work was done to a very high standard. We are really pleased with the result. This extension has freed up space in the garage for my woodworking hobby. We will definitely be coming back to Nathan to quote for future building projects. Now that I have my woodworking man cave my wife has started thinking about the kitchen...

Chris is very professional. He had clear and prompt communication with me from the start. Quoted a reasonable price and didn’t sneak in any extra charges in the end. Very flexible when we had to make changes to the time originally booked for the job. The job has been done to a high standard. I will definitely use his services again for work in future.

Kitchen Fitting- 14 Jan 2026
My initial experience with Solis Power Limited was Leo’s immediate response within 30 minutes, visited my property to view my kitchen. He gave a full detailed breakdown of price list that explains each work to be carried out. Suggested materials to use also help with the purchase. Leo and his team are perfect working together, cleaned after themselves each day. They installed new electrical unit, also introduced registered gas man to run gas pipes and also connect the gas hob. Plumbing work was excellent too. Leo also helped with the measurements of splashback and splash splatter guard. The work was carried out within five working days delay was due to shortage of splashback in the store. I highly recommend Leo and his team.

What qualifications and experience do you have as an extension builder in Clapham Junction?

An extension builder in Clapham Junction 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.

What experience do you have with similar extensions in Clapham Junction?

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