Breathable Lime
No reviews yet
Extension Builder in Hoxton
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.

My colleague referred me to Raed who previously have had used R.Hamandi Ltd for construction work and they were very happy with the quality of service. Along with some other building company's last year I also contacted Raed for an estimate. Raed gave us a reasonable price with all the details of proposed work. He also explained about the possible options of how we could get the best value for our money. His professional and friendly advice helped us a lot to understand what exactly we needed and what was best for us to go ahead for our project. We decided to go ahead with R.Hamandi ltd. Raed gave us breakdown of the project and everything was documented. His support in communicating with council and planning related issues was valuable. All the planning permission requirements were followed. Presence of experienced and trust worthy staff including laborers, handymen, carpenters and painters really made it easy for me and family to be around and comfortable while they were working or to leave the house whenever we had to. Raed himself used to visit the site everyday to oversee the progress and used to discuss and take care of any possible issues. Raed's team used to turn up on time and the project was finished on time too. Even after the completion of the project staff at R.Hamandi ltd and Raed himself contacted us few times to find out if we're happy with the work carried out or if we needed any further assistance. Now we have a fully refurbed house with double side extension and loft conversion. Overall amazing service, professional, reliable and trustworthy. I recommend R.Hamandi ltd to everyone for an A+ service. Thanks,
Amazing constructions limited

Electrical- 26 Jul 2026
Genuinely one of the worst builders we have come across. David rewired the flat and Stefan plastered the hallway. David is NOT qualified as an electrician and cut corners wherever he could. David leveraged us for money mid job and in the end left the job without finishing and without providing a certificate. David ran cables behind door frames (awful idea), got the cheapest material, forgot where holes were for spotlights and switches among many issues which meant we had to constantly ask our builders to fill the holes and make good. Stefan did the hallway plastering without putting on mesh. The plaster cracked within 2 weeks and the paint keeps cracking and will be a constant problem. When asked to come back and fix the issue - he point blank refused. They were the cheapest quote but we really hope we had gone to someone else

Restoration & Refurbishment- 3 Mar 2016
Paul has done the most incredible job on my listed cottage. He's passionate about the building, works to an extremely high standard and does what he says he is going to do, and more, without ever going over budget. Paul has completed a large amount of difficult structural work as well as fully re-fitting the kitchen and bathroom and I will be using him for much more work on the house in the future. I cannot recommend him highly enough.

What to ask a Hoxton extension builder before hiring?

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

An extension builder in Hoxton 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 Hoxton 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 Hoxton?

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 Hoxton 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 Hoxton 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.
