It usually starts with a dark grey patch on the wall. The next thing you know, your entire room starts smelling like old socks. And like every problem we’ve ever had, we start blaming it all on the British weather.
Damp is our one true enemy, affecting everything from our homes to our health. It’s only wise to start with preventing it from spreading; otherwise, we’re putting ourselves at risk for costly repairs.
For top-notch services, we found London’s most reliable damp proofing contractors. This list is a result of local homeowners’ insights, recent work projects, and current market data.
How much does damp proofing cost in London?
The cost of damp proofing services in London ranges from £1,000 to £5,000. This depends on the size of the property, type of service, and scale of the issue.
How we chose the best damp proofing services in London
- Service Range: We considered the range of services, including surveys, diagnostics, treatments, DPC installation, and more.
- Pricing: We assessed how clear and fair each company’s pricing was. Flexible payment options were also considered.
- Guarantees and Aftercare Support: We examined the coverage and level of support provided post-service. Response to post-treatment concerns was taken into account.
- Flexibility and Availability: We evaluated how flexible each company is when it comes to booking and scheduling. Those who can work beyond hours were prioritised.
1. E K Damp Proofing
Location: Seymour Rd, London
Contact: +44 7956 219045
Opening Hours: Open 24 Hours
E K Damp Proofing is a reliable choice for fast, same-day emergencies. They answer on time and arrive promptly, immediately diagnosing the issue.
Their fair and transparent rates won us. They stick to quoted rates and are even willing to complete additional small tasks at no extra charge.
The custom-first approach is also evident. For instance, when drying times aren’t ideal on that day, they’ll adjust schedules to come back the next day.
We appreciate this approach more than those who push for projects without certainty.
We love the level of workmanship too. During the job, they keep the entire site tidy and leave it spotless once done.
The results are impressive. Most clients have nothing but praise for their precision and lasting solutions.
However, they’re not a very large team. If you have a large property, you may be better off working with a more capable company.
This may also affect their availability during busy periods, before and after winter.
Did a good job
“Elvis was great. Quick to respond and communicated regularly. Did a good job and for the quoted price. He even did some additional work we had asked about for no extra charge. Elvis is a nice guy too so we would recommend.”
– Thomas Clark, Google Review
High standard and competitive pricing
“Elvis did a top job putting a damp course in my basement. The work was done to a high standard and completed to budget and on time. I would recommend the company to anyone who needs damp repair in their home.”

2. London Damp Proofing
Opening Hours: Open 24 Hours
London Damp Proofing offers a wide range of services. They target rising damp, penetrating damp, and basement tanking.
With over 16 years of experience, reliability is clear. Clients also get detailed explanations for their projects, so they know exactly what’s done.
They consistently complete work ahead of schedule. As confirmed by multiple client stories, the quality of work wasn’t compromised.
In fact, they’re exceptionally tidy. Items are protected with coverings, and results are precise enough to ensure lasting outcomes.
And of course, we love their 30-year guarantee on all chemical damp-proof course treatments.
Reassurance also extends to their overall attitude. Assessments are honest, leading to fair quotes without hidden fees during surveys.
They keep clients in the loop, too. Our team saw how quickly they responded to both texts and calls when we requested quotes ourselves.
We just heard a few complaints about the unprofessional staff attitude. However, this doesn’t appear to be the norm.
Prompt and reasonably priced
“London Damp Proofing are fantastic! They’re always quick and responsive, get their quotes out promptly, and are very reasonably priced. Steve and his team are professional, reliable, and a pleasure to work with. Highly recommended!”
– Colin Shepherd, Google Review
Speedy and top-notch service
“We had our cellar waterproofed by the team with new membrane wall and flooring. The workmanship was top notch and the job was done ahead of schedule. Steve is very responsive which is always appreciated for this type of work. No complaints and highly recommended.”

3. Crown Preservation Damp Proofing
Location: 78 York St, London
Contact: +44 20 7412 8267
Opening Hours: Monday – Friday: 9:00 AM – 5:00 PM
Crown Preservation has over 30 years of specialist experience. Their team is highly skilled in diagnosing a wide range of damp causes.
We love how broad their services are. Some of their best-known solutions include rising damp treatment, condensation solutions, and woodworm treatments.
The work process is efficient. Through their approach, clients are happy to note that the results were effective.
The finishes were also tidy and well-organised.
Even their administrative management deserves their flowers. We appreciate how dependable they are with paperwork. This ensures clients receive accurate and honest assessments without upselling.
Communication is also a pretty solid area. When we first reached out, we were impressed at how promptly they replied. Support is also ongoing before, during, and after the job.
We only heard a few of the typical complaints, with one client sharing that the crew arrived later than promised.
More complex projects may also put clients on the waiting list, which affects wait times.
Professional, knowledgeable, and helpful
“I have just had Daniel over for a damp survey. He was so professional, knowledgeable, and helpful, and really put my mind at ease about a damp issue that had been keeping me awake at night. I then called the office and spoke to Declan, who clearly explained what was involved. This is a true old school family business, and I will write another review after the work is completed.”
– Paul M, Google Review
Hard-working and efficient
“From start to finish Declan has been on hand to answer any questions I had. The labourers Rob and Valentino where excellent, hard working and efficient. Each night they made sure they cleaned up not leaving a mess and everything was done in a professional manner. The work was to a great standard. Even when the job docket was slightly wrong, Declan sorted it out no problems. Did a great job overall.”

4. London Roofing and Damp Proofing LTD
Location: Riverbank house, 1 Putney Bridge Approach, London
Contact: +44 7729 325307
Opening Hours: Open 24 Hours
What we liked the most about this company is how fast they are when responding to emergencies. They often arrive within 24 hours and are able to complete full repairs within the promised time.
The quotes are great, too. We like how clients can easily receive an estimate within the day. Once they proceed, the numbers will be honoured as well.
However, they’re actually not the cheapest option in this list. And while they’re not extra expensive, it can be a substantial total for big jobs.
The value for money is clear in the quality of work. Clients highlighted durable repairs, clean finishing, and tidy workspaces.
We also appreciate the little things, like the visible improvements in fascia renewals.
Documentation is also a strong point here. Every work done involves photos at every stage.
For clients, this helps them understand root causes and solutions implemented.
They also follow up on the projects they finish to ensure that everything is up to standard.
Great service at a reasonable price
“Billy and Eddie were a breath of fresh air. Our bay window wall was peeling with damp and needed the full works (rip out, rebuild inside, rebuild outside & redirect gutter & full damp treatment). Unlike some damp proofing companies who just fix the damp but then don’t rebuild/redecorate, because they’re also a full building company they did it all (and for a fair price). They’re also always smiling and chirpy which, when people are in your house for a few days, really makes a difference.
I’d definately recommend.”
– Louise Rowntree, Google Review
Excellent standards of work
“I recently required some roofing works and contacted London Roofing for a quote. Billy came the next day to view the work and I received a quote later that day. They carried out the work to an excellent standard. Billy and Eddie are very professional in the way they carry out their work and have a very nice manner.”
– Heather Greenslade, Google Review
5. Advanced Damp Ltd
Location: 45 Fitzroy St, London W1T 6EB
Contact: +44 300 373 7251
Opening Hours: Monday – Saturday: 8:00 AM – 6:00 PM
Advanced Damp LTD is great for its technical expertise. Their team is knowledgeable about inspections, helping them accurately diagnose the main issues.
The range of services is solid. They offer pretty much everything from ventilation installation to DPC installations.
The quality of work is just as great across all job types. The team protectively surrounds the area and works cleanly to leave the home spotless.
According to client stories, the results are considerably long-lasting.
Their client-first attitude is evident at every point. Surveys are scheduled promptly, and the treatment process is started without any delays.
We also love how their local technicians are trained to the same standards. In a way, this helps maintain consistent quality results.
Like most businesses in this industry, expect that services get booked fast during peak season. We advise booking a month in advance during busy months.
And while most of their basic services are priced competitively, some are relatively higher.
Professional, courteous, and highly skilled
“Advanced Damp exceeded my expectations with their exceptional service and expertise. Their comprehensive range of services and guarantee-backed work provided peace of mind. Professional, courteous, and highly skilled, they made my home safe again. Highly recommended!|”
– Olivia Anthony, Google Review
Explained everything clearly
“After noticing some damp patches in our living room, we decided to call Advanced Damp. They sent Robert over for a survey, and he was thorough and explained everything clearly. We went ahead with the recommended work, and the issue was resolved quickly. Very happy with their service!”
– Alina Fjodorova, Google Review
