1. London PDP Ltd
Location: 115 Grove Rd., Bow
Contact: +44 20 8980 7221
Operating hours:
- Monday to Friday – 9:00 AM to 5:30 AM
London PDP Ltd caught our eye for their no-nonsense approach to damp proofing and basement waterproofing. What we appreciated most when we looked into their services was how thoroughly they assess each property – no guesswork here.
They start with a detailed inspection and deliver a clear, honest quote that only covers what’s actually needed. There’s no upselling or fluff.
Customers we spoke to love the team’s straightforward attitude. Plus, their pricing is quite fair, especially for the quality they deliver.
One small thing we noticed, though, was some feedback about unresponsiveness at times, which is a shame since the rest of their service is solid.
But overall, we were impressed with London PDP Ltd’s dedication to reliability.
Arranges visits easily and punctually
“Having had Adrian solve our damp problem in the basement 6 years ago, I called him when a separate problem arose. It was very easy to arrange a visit, and he came on time – not always a given! It turned out not to be a damp-proofing issue that he deals with, but he stayed to look at the problem and give advice as to who best to contact, which was so helpful. Really impressed with this service.”
Richard Bowman, Google Review
Offers genuine and personalised service with no pressure
“We had a great experience with Adrian. Moved into an old Victorian house with damp issues, and he was incredibly generous with his time. He spent about 20mins talking through the issues free of charge over the phone, with no obligation to book a visit. Then when we did book a visit, he was very thorough, pragmatic, and explained everything we needed to do about 3 times to help us really understand the issue. If you want a genuine personalised service, and high quality, cost-effective advice, we honestly can’t recommend London PDP enough!”

Contact: +44 7520 665321
Operating hours:
- Monday to Friday – 8:00 AM to 5:30 AM
Basement Construction and Waterproofing has earned its place on our list for its exceptional work in transforming basements into vibrant, usable spaces.
They specialise in basement construction, conversions, and the DELTA Waterproofing system. This expertise makes them well-equipped to keep London’s notorious dampness at bay.
We love that they guide clients every step of the way, from sketching the initial concept to putting on the finishing touches.
Their online platform is a breeze to navigate. It has tons of information, a project gallery, and an easy contact form for questions or quotes. It’s a nice touch, especially for busy homeowners who want to get started with just a click.
The only catch? They’re in high demand, so booking them might mean a bit of a wait. If you’re considering them, we’d recommend reaching out soon to secure a spot.

3. City Waterproofing LTD
Location: 1, Orchard House, County Grove
Contact: +44 20 3633 2539
Operating hours:
- Monday to Saturday – 8:00 AM to 5:30 AM
City Waterproofing LTD has a special charm that comes from being family-run with over 15 years in the business.
Their expertise with damp-proofing is rock-solid. They cover everything from wet rot and dry rot to rising dampness in both homes and commercial spaces.
When we looked into their services, we were impressed by how dedicated they are to using the latest technology and methods. This shows they’re truly committed to delivering effective, modern solutions.
What really sets them apart, though, is their free initial survey with qualified CSSW surveyors. Customers we spoke to found it especially helpful for receiving an expert assessment without any upfront cost.
Plus, it’s easy to reach out through their website. You can even get a quick quote online. We thought it was a nice touch for those wanting to plan ahead.
The only drawback? Some customers noted slightly higher pricing. But considering the quality and service, we think the price is worth it.
Completes damp proofing efficiently and on time
“Armond and his team did our damp proofing ground floor property. They were amazing from the start to finish. They managed to do the job very professionally, cleaned everything, and finished on time. I would definitely recommend them.”

Transforms damp spaces into functional and usable areas
“Armond and his team completed both the damp proofing and finishing work in my cellar as well as the plastering in our bedroom. The work is super high standard and Armond and the guys were extremely proactive and solution oriented in their approach. Really happy with the overall finish and turned a damp clay pit into a useable storage space and washroom. Would highly recommend.”

4. E K Damp Proofing
Location: Seymour Rd
Contact: +44 7956 219045
Operating hours: Open 24 hours
E K Damp Proofing has been around since 1990, and it’s clear why they’re trusted in the waterproofing world.
With over 25 years in the game, they handle everything from damp-proofing and dry rot removal to air ventilation solutions.
We liked that they’re not just experienced but also up-to-date with high-quality materials and modern tech. This includes using DPC injections to keep dampness at bay for the long haul.
One thing we found really convenient is their 24/7 availability; not many companies offer that kind of responsiveness.
Plus, they provide services for both homes and businesses. Even better, they offer free estimates, so it’s easy to reach out and get an idea of what’s involved.
A quick note, though: with their popularity, they book up fast, so we’d suggest getting in touch early if you’re interested.
Provides excellent workmanship and thorough answers
“Elvis recently opened up, damp proofed, and plastered a wall in our home – from start to finish the job was smooth and professional. Elvis answered all our questions and did an excellent job, as well as generally being friendly throughout. If you’re looking for someone skilled at damp proofing, look no further than Elvis!”
Jake Francis, Google Review
Balances professionalism with a friendly and approachable demeanour
“We’ve used Elvis’ services twice now: first to clean and fix our gutter, and recently to damp proof our front room. He did a great job, taking care to protect our belongings and keeping us informed of his progress throughout. Doesn’t hurt that he’s always ready with a smile and a pleasure to talk to. Would definitely recommend.”

5. Creative Contracts Uk Ltd
Location: S V S House, 2B Oliver Grove
Contact: +44 20 8407 0154
Operating hours: Open 24 hours
Creative Contracts UK Ltd offers a fantastic range of services to tackle almost any moisture-related issue.
From structural waterproofing and basement tanking to dry rot and timber preservation, they seem to cover it all.
What really impressed us, though, is their status as Triton Approved Contractors. This speaks volumes about their commitment to high-quality work and strict industry standards.
With over 25 years in the business, Creative Contracts has a reputation for reliability. Moreover, their insurance-backed guarantees that range from 10 to 20 years offer peace of mind that their work will last.
Homeowners can even get a free damp and timber survey, which is a huge bonus for catching potential issues early.
Their website is simple to navigate, making it easy to explore their services and schedule a survey. They’re available 24/7, but a heads-up – during peak hours, reaching them might take a bit longer.
Identifies and repairs extra areas at no added cost
“James from Creative contracts, came around to assess a very damp wall I had in my extension. He gave me a price and we agreed a start date. On the day the work was due to start the guys arrived on time and got down to work straight away. At the end of the day they left the place clean, tidy and locked up for me afterwards. The following day they again arrived on time and completed the job. Again sweeping up and leaving the entire space clean and tidy. They swept the outside area up as well where there was a bit of dust / cement. They found a few extra areas that needed repair and didn’t charge. I can’t recommend them enough and will be using them again. I will certainly be calling on James and the team in the future. Great guys, great job and a decent price.”
Mr Prince, Google Review
Maintains a clean and tidy workspace throughout
“Creative Contracts came to sort out a small area of damp in my house recently. James, a friendly and kind man, responded immediately, assessed the problem and reassured me that it wasn’t a big job. He and John subsequently came and carried out the work very well. They left everything very tidy. I heartily recommend them for the thoroughness of their work. It was also very reassuring to have such pleasant people working in my house.”
