Brilliant and professional

Brilliant and professional job done. Paul arrived and gave me his quote for the job.

On the appointed day, he and his assistant turned up on time and did the job with due attention to even the smallest details.

The job was completed to very good standards and has so far (2 months and counting) stood the test of time.

If you are considering whether to employ Paul, just go ahead. His standards are very high and it's very unlikely you will be disappointed.

beagooner - Sept 2016

Pleasant and polite

As stated in previous reviews work was carried out very professionally.

Paul replied promptly to my request, visited soon afterwards and gave me advice.

He quoted a very reasonable price. I was so impressed I didn't even bother to get other quotes! Work was carried out by Alex and Paul.

They were both pleasant and polite. Everything was cleared away out of sight overnight and when they left the following day both rooms they had worked in were spotless.

I would strongly recommend this company and would not hesitate to use them again.

Paula Symons - Nov 2016

Very much recommended

We had a number of large patches of damp. Some of these were being caused by water ingress from outside.

Paul was prompt to respond to the myBuilder post and came round and quoted very quickly.

His team was happy to work in the house while we were having a rewire at the same time which was very helpful for us in terms of minimising the disruption.

Paul’s team removed radiators, applied appropriate damp treatment and even raised a couple of air bricks outside to stop rainwater coming in.

I would very much recommend Paul and his team.

Jim Peacock - May 2017

Very competitive quote

Paul came and gave a very competitive quote at a time that was convenient to me. The 30 year guarantee is also a big plus!

He completed the work in 3 days, and so far we don't have any signs of damp. He cleaned up thoroughly afterwards, and I'm very happy with the work. There was also a few extra jobs outside the house which Paul did as part of the job, even though he didn't have to.

The only minor thing I would say is that communication is a bit brief, but that had no reflection on the quality of the work carried out.

I'd recommend using London Damp Proofing if you've got a damp problem!

Cait Harvey - Nov 2016

Polite, courteous and professional

Paul was polite, courteous and professional at all times.

His work partner Alex came and completed the job.

I've dealt with lots of building companies and builders and none have been as efficient, tidy and mindful of the clients surroundings as Alex was.

He had a brilliant personality and his attention to detail was spot on.

I would recommend Paul and Alex to anyone.

user_246r - March 2017

Very professional service

Very professional service from Paul and his team.

Paul came first to give a quote for the works - the quote was reasonable and fair. He then provided me with a date the works could be done.

His man turned up on time, did exactly what Paul had explained in advance and left the whole area clean and tidy.

It was a pretty straightforward process.

I would certainly recommend London Damp Specialists and would use them again in the future.

ktrngnst - Sept 2017

Highly recommended

The work was carried out quickly and efficiently.

Very impressed with reliability and work carried out.

Talks through and explains all aspect of work before starting.

Maintains contact throughout job.

Would not hesitate to recommend.

Ebigail H - Nov 2016

Care and precision.

I hired Paul to re-plaster two internal walls due to a penetrating damp issue.

Paul gave a competitive quote and explained exactly what he was going to do before starting the job.

The job took 2 days to complete. Paul kept me up to date with his progress and performed the job with care and precision.

He was trustworthy and on the second day I let him work alone in the house while I was at work. He took care in cleaning up after him too which was a bonus.

I have no problem in recommending him to others.

Sebastian M - Sept 2016

Absolutely stunning job

What an absolutely stunning job! I'm usually too lazy or too busy to leave reviews...but on this occasion I just MUST leave one.

I left for work with an incredibly uneven, cracking, poor attempt at damp proofing my kitchen. I returned to find Paul had already left... and the kitchen walls... well, wow, wow, wow.

They'd obviously been stripped right back, completely re-plastered and were now straight, totally even and as smooth as ice.

I was absolutely stunned.I honestly can't rate Paul highly enough and I have absolutely no hesitation in recommending him.

If you want a truly professional, platinum grade job done at a very reasonable price, hire Paul - you will not be disappointed.

Sarah J - Sept 2016


Excellent work from Paul and his team.

Quote was fair and work was undertaken fairly soon.

They protected the floors and tidied up afterwards with barely any sign of them having been in, impressive considering the scope of work done.

It's now two months on and no signs of damp.

Thanks Paul.

Mike D - Sept 16

Big job done to a great standard

Excellent work.

We got London Damp Specialists to damp proof our basement.

It was a pretty big job but they done it to a great standard and they where quick and clean.

It has been months now since the work has been completed and its all painted and it looks fantastic and dry 🙂

They are a great friendly bunch of lads.

Thank you!

If left untreated, damp will start to affect the structure of your property, causing extensive damage and effecting the value of your home.

Damp Treatments in London

The geology of many London areas consists of clay materials and many areas are susceptible to flooding. These two aspects means that many basement flats and cellars can require damp proofing or basement tanking to keep them habitable.

If your home shows signs of damp you already know how unsightly the problem can become. As well as affecting the value of your home, damp frequently gives rise to mould which in turn can affect your respiratory and immune system.

Don’t despair, with prompt diagnosis and treatment the underlying causes can be addressed and structural damage repaired.
