Homebuyers Damp Report

If you’re buying a new home or property in the London area, you may need a professional damp survey. A thorough damp survey from a professional will look for all and any types of damp in the property and could help save you thousands of pounds. London Damp Specialists is on hand to carry out your damp and timber report.

Request a Survey

Many properties on the market for sale have had quick fix and cheap damp repairs just to sell. It’s not until a few months after you move in that the damp and condensation issues start to creep back. They might start showing themselves with horrible mould and damp patches reappearing. Occasionally, the extent and severity of the dampness in a property will force you to vacate while renovations are done and the inside is revamped – extra cost and upheaval on top of moving.

But call London Damp Specialists before you exchange contracts and we will carry out a damp report that can find hidden and underlying issues that may not be visible to the naked eye. We use the most advanced technology available to give you peace of mind that your new home is free of damp.

Nearly every old property has some sort of damp, and if there is damp, we will find it.

Damp Survey Costs

We have three levels of Damp survey as well as an extra lab analysis of affected plaster. You can choose from:

Level 1 Survey: £199 + VAT

This survey includes an inspection of all interior and exterior walls and floors for signs of dampness and leaks.

Level 2 Survey: £299 + VAT

This includes everything from Level 1, plus an examination of all wood structures and loft timbers for wood rot and woodworm.

Level 3 Survey: £399 + VAT

This survey includes the same checks as Level 2, with the addition of thermal imaging, air humidity testing, borescope camera, drone imagery and ventilation flow test.

If you’re unsure of the level of survey you need, please call us on 020 8528 3864.

We can schedule the Damp survey within a few days, and we’ll send a comprehensive report and findings to you within 24 hours, along with a quote for any necessary work. That way you can quickly decide on next steps.

If you then ask us to carry out the work needed to fix the issue, we’ll take the cost of the survey off the price of the work.

What Should You Do if Damp is Discovered?

The first thing to do if we uncover damp during our survey is – don’t panic! The very word ‘damp’ can strike fear into a homeowner or buyer but it isn’t necessarily always doom and gloom. We will be happy to discuss our survey’s findings with you so you know the full extent of the issue, the levels of repair needed, the costs and the potential disruption to you and your family.

Armed with this information, you can then make a call on whether to go ahead with the house purchase. If you have your heart set on the property, the cost of repairs may well be outweighed by the time you’ll spend living there. We’re always happy to discuss damp issues with you.

Damp Meter

This device has multi-purpose use; it can identify problem areas, pinpoint sources of damp and monitor if areas are drying out over time. The meter can be calibrated for timber or plaster and there are two main types, namely pinned and pinless damp meters. The pins can be inserted into timber or mortar to accurately measure the moisture content within the material, while the pinless variety measures surface moisture.

Thermal imaging camera

This is a device that locates potential areas of damp on walls, ceilings and floors, visualising temperature differences on the surface of materials. Damp areas are typically cooler than dry areas and this shows on the screen; Thermal imagery is primarily used for masonry diagnosis and is an indispensable piece of equipment for a damp surveyor.

Humidity Testing

A device to measure the level of humidity in the air; the handheld device is very accurate and helps the surveyor to get an overall assessment of the moisture content in the air. If the surveyor is looking for mould, measuring humidity will show if mould could grow in that area. An integral device and one of the first tests to be carried out.

Colour Inspection Borescope

This type of camera is very useful for looking at hard-to-reach places, such as wall cavities, under floors and to determine the wall structure in some building types. Also known as a pin hole camera, this device can detect leaks and is used on every survey to get a close-up of targeted areas and the surveyor can investigate an area with hi-res imagery.

Drone Imagery

Used to inspect the exterior of a building, state-of-the-art drones bring hi-res close ups of the roof, guttering and upper walls, while it enables the surveyor to check for missing roof shingles. This saves time, which is a win-win for everyone and any issues can be investigated further. Every damp survey would include scanning the exterior with a drone, looking for defects and signs of damp, zooming in when necessary.

Ventilation Flow Test

Ventilation is essential to reduce the moisture in the air and to determine the degree of airflow, the surveyor has a range of devices in their arsenal. Mould and mildew thrive in still, humid conditions and by generating an airflow, you can dry out the air, which helps to prevent dangerous fungi forming.

Lab Analysis of Plaster

An additional service of plaster lab analysis is available, with up to 10 plaster samples tested to prove moisture source. This is an accurate way to assess moisture in walls, with lab analysis of the samples.

FAQs

Does the weather impact damp in houses?

Long periods of dull and wet weather create the perfect conditions for damp and mould to thrive and we haven’t seen the Sun for months. Heavy rainfall is sure to cause damp issues to older properties.

Is there a warranty on damp proofing services?

We are proud to issue a comprehensive 30-year guarantee. If any area that we have repaired requires further work, we are happy to carry out the work at no cost to the customer. This is a reflection of our high standard of workmanship and we have a great reputation within the industry.

What does a homebuyer damp survey cost?

The cost depends on the level of survey you choose; check our homebuyer survey page for details and prices. We also offer an add-on service, lab analysis of plaster samples taken from various locations. The cost of the survey is deducted from the cost of the remedial work.

Would the surveyor take photos?

Yes, our surveyors do take photos in order to show the customer specific areas.

What equipment does a damp surveyor need to do his job?

Our surveyors have an array of tools, equipment and devices; thermal imaging cameras, moisture meters (both varieties), borescope cameras and they also use drone imagery. A surveyor would even have spares, while our damp proofing teams have fully equipped mobile workshops.

Is it possible to work on a building at any time of the year?

Damp surveys and remedial work can be carried out year-round and winter is likely to be less convenient for the occupants. Sometimes it is necessary to zone off the property until the work is completed.
