Conversions - General- 22 Jun 2026
Bled from BSM was fantastic from the start of the job to the finish. His pricing was fair, and he turned up each day on time, and left everything tidy each day. Nothing was too much effort, and the quality of the work was outstanding. I would have no hesitation in recommending him to anyone else.

Extensions- 22 Aug 2022
Jagdeep and his team have been great. He is very polite and throughout the whole project we got along very well. He has done a great job for the complete project. I have asked him to come back to more and more work. It started off with a 16m2 bungalow, then 60m2 driveway then another 60m2 porcelain patio with stainless handrails. He has built the bungalow extension with complex steels. His brick work is fantastic, all the other brickys have said the work looks very good. He is was good keeping to our agreed price, and when I have asked him to do extra work his pricing has been very honest. If I ever have another project like this again, I would choose Jagdeep again.

Restoration & Refurbishment- 25 Feb 2020
Malcolm and his team did great work on my house. The job consisted of full house redecoration, building bespoke shelving and built in wardrobes, loft boarding and installing ladder, replacing fencing and general pruning in the garden. They were able to turn their hands to all manner of jobs. Malcolm had a full team onsite every day and they finished the work ahead of schedule. At all times Malcolm was very responsive and worked hard to ensure that any changes along the way were accommodated. I would happily recommend Spring Construction and would not hesitate to use them again in the future.

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

An extension builder in Hounslow 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 Hounslow 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 Hounslow?

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