Pawel and his team are great - got them in for a few things now, from damp repair, knocking through an internal brick wall, moving a fuse box, installing a wood floor. Always good workmanship, easy comms and decent value! Have recommended to a few friends who are equally pleased.

Extensions- 1 Jul 2021
Great job done by Naim and his team. He expressed interest in the job as soon as I posted. If it hadn't been for some wet weather the job would have been completed much sooner in the timescale he quoted. There was one small issue some time after the job was completed. I only called Naim once and he arranged a day to come fix it. We're very pleased with the finish, we would give future work to him and also recommend him to friends & family.

Breathable Lime
No reviews yet
Extension Builder in Sydenham
Breathable Lime are lime plastering and damp specialists for Victorian, period and listed homes across south and east London, Kent and Essex. Most damp in older properties isn't rising damp. It's moisture trapped in the walls by cement render, gypsum plaster and vinyl paints. Victorian homes have solid walls built to absorb a little moisture and let it evaporate. Modern, impermeable materials break that cycle, causing persistent damp, black mould, blown plaster and cold, musty rooms. We fix the root cause. Using Breathaplasta, a modern hemp lime plaster by Adaptavate, we restore your walls' breathability without cement, gypsum or plastics. It regulates moisture, resists mould, flexes with the building and sets in around two hours per coat, so it's far quicker and less disruptive than traditional lime. Every job starts with diagnosing the real cause of the damp. No unnecessary chemical damp-proof courses, injected treatments or tanking, just honest advice and a permanent, breathable solution. Free, no-obligation quotes.

What to ask a Sydenham extension builder before hiring?

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

An extension builder in Sydenham 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 Sydenham 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 Sydenham?

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 Sydenham 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 Sydenham 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.
