“Perry came and surveyed our 1850's cottage and was very knowledgeable on old buildings. He reassured us after a damp solution company came in and wanted to do some questionable retro fitting works.
I would highly recommend Pro Check for damp and timber surveys. Especially as they are independent and have no agenda to sell any products.”

Frequently Asked Questions

What is a damp survey?

A damp survey is a detailed inspection of a property to identify the cause of moisture issues such as damp patches, mould growth, condensation, penetrating damp, or timber decay. We provide clear findings and honest recommendations based on the condition of the property.

What areas do you cover for inspections?

We serve homeowners and property professionals across London, Essex, Kent, Surrey, Hertfordshire and beyond.

How long does a typical inspection take?

A typical inspection can take anywhere from 1-3 hours, depending on the size and complexity of the property.

What are the benefits of having a damp survey?

A damp survey provides clear, expert insight into the condition of a property, helping you understand not just if there’s a problem, but exactly what it is, why it’s happening, and how to fix it.

One of the main benefits is early detection. Damp issues often start subtly but can lead to serious structural damage, timber decay, and costly repairs if left untreated. A professional survey identifies these issues early, saving you money and stress in the long run.

You also get accurate, unbiased advice. Rather than guesswork or relying on contractors who may have a vested interest in selling treatments, a proper survey gives you a clear diagnosis and practical, actionable recommendations tailored to the property.

Should I get a survey carried out before I purchase a property?

Yes, it’s highly recommended.

A damp survey can uncover hidden issues that standard surveys often miss, helping you avoid costly surprises after purchase. It also gives you the chance to renegotiate the price or plan for any necessary repairs.

Most importantly, it gives you confidence that you know exactly what you’re buying.

Do you treat mould?

Yes. We can inspect, identify the cause of mould growth, and provide mould removal and prevention recommendations where required.

Will I receive a written report?

Yes. All surveys include a written report outlining our findings, moisture readings, photographs, and recommendations. Surveys are issued the very next working day - Guaranteed!

How quickly can you attend?

We aim to offer appointments as quickly as possible and can often attend within a few days depending on location and availability.
