Breathable Lime
No reviews yet
Extension Builder in Earlsfield
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.

Restoration & Refurbishment- 2 Apr 2026
Really pleased I chose Leigh Matthews for this job. We were taking over a building that was unoccupied for 18 months and there were some issues with that, The team were excellent, and they finished the 4-week job on time, and right on budget. They were helpful and considerate and left the premises clean and tidy. They were also able to help out with some problems with the plumbing that were not in the original scope. I loved the way they did the estimate and the invoicing. Breaking all the items down into the individual tasks and at the end of each week, itemising which tasks were complete and a %age on those in progress. I would not hesitate to employ them again

Carpentry- 7 Sep 2021
The cladding was due to start yesterday, Monday 6th of September. In the weekend, I was told they would come do a site visit on Monday instead of starting the job. They came on site yesterday morning and nothing was said about any issues. They said they would start the next day, Tuesday. I got a call at the end of the afternoon (around 5 pm) yesterday to be told suddenly that there are many problems; not levelled portions of frame (which can be easily rectified), no toilet on site (which they knew about - they knew also that the public toilet is only 50 m away), access problems which they also knew about ect... Suddenly a multitude of problems arised! They wanted more money. It is very obvious that they found another job somewhere. I would classify this sort of behaviour simply as not honest. Also expensive- I was quoted £4000 to clad a tiny first-floor(38 m2) . The overall cladding would be 75 m2 in total. Disappointing.

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

An extension builder in Earlsfield 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?

What experience do you have with similar extensions in Earlsfield?

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