How to Find a Damp Surveyor in London


To understand how to locate the best damp specialist if you are a London-based property owner, you need to clarify initially what issues you are experiencing that might need a damp assessment.

If left untreated, damp can cause severe infrastructural damage to a building. Water ingress is not always as dramatic as a flood, but slow and insidious and not easily discernible, which is why it is important to investigate as soon as you are aware of a potential issue.

If you walk into your property and detect an underlying smell of mustiness, if there are patches of damp creeping across the walls around chimney breasts or rising up from floor level, if there are areas of black mould across the walls and ceiling, then you know you need to seek out a damp specialist. But with so many to choose from in the UK’s capital city, what’s the best way of finding one, and how can you tell if they are reputable or not?

It would also be helpful for a potential damp and mould surveyor to know if you are an individual homeowner or if you are a commercial or residential landlord. While the problems are similar, often, the solution has slightly different applications and approaches.

Google ‘Damp Assessment Near Me’

These days, the most used method of searching for a reputable trade company, such as a plumber, electrician, or, in the case of Garratt’s, a damp expert, is to use Google. One of the most significant updates in Google’s search algorithms recently was the implementation of more localised search criteria, which will highlight locally verified businesses and any company that is established will have a Google My Business profile with genuine online testimonials.

If you are London-based and searching for damp surveys in London or damp surveyors near me, Garratt’s Damp & Timber Ltd. will be high up on the list of suggestions, and with over 75 verified positive reviews, we are confident that you will understand the reassurance that these endorsements will give you when seeking a solution for your damp issues.

Trade-Specific Listing Websites

There are a number of specialised websites that you will probably have seen advertised on your local radio and TV channels - listings sites such as My Builder and

To get listed on these sites, you need to fulfil a certain number of eligibility criteria, such as proof of professional indemnity insurance, as well as any professional certifications and qualifications required for you to practice your trade within established regulations.

Word of Mouth

There’s no better recommendation than word of mouth. Hearing from someone’s personal experience of having dealt successfully with a damp problem will save you hours of hard search, as well as potentially thousands of pounds.

Garratt’s is a family-run business that has been in operation for more than 20 years and has thousands of successful installations under its belt. The company has been featured on the local news, commenting on damp problems in social housing. Its reputation and professionalism stand firm among other damp surveyors in London.

Having said that, do not always rely on word of mouth. One person’s success story can sometimes be another person’s nightmare, and Garratt’s will always encourage you to consult with other damp proof surveyors when looking for professional advice - if only because it is confident in its service and pricing.

What to Expect When You Book a Damp Assessment

Once you have shortlisted the dampness surveyors you feel fulfil your own selection criteria, then they will need to visit your site to carry out the survey.

The damp surveyors will visit your property at an appropriate time, work with you to discover the issue and then advise you based on what’s best for your individual situation.

Do not succumb to hard-sell tactics - a reputable company will never try to push you into paying for expensive remedial work that is not necessary. Surveyors are just that - damp surveyors who take a professional expert’s evaluation of your problems. They are not salespeople.
