Independent damp and
timber surveyors

Preservatech UK Ltd are independent damp and timber surveyors and building defects consultants based in the northwest of England.

We hold the CSRT qualification as assessed by the PCA, (Property Care Association) which is nationally recognised and approved by mortgage lenders.

We have previously worked as contractors in the building preservation sector for nearly 40 years and have been Federation of Master Builders members for over 20 years, giving us a vast amount of knowledge and experience in building construction.

Our aim is to provide honest professional advice and inspection of any defects affected by moisture which could lead to expensive repairs and provide a cost-effective solution.

All our surveys are chargeable based on the size of the property. POA. We are not affiliated with any suppliers or contractors and give totally independent advice.

Why choose us?

We are one of only a handful of companies to provide a full in-house service from drone roof surveys to underground CCTV drain inspections. This eliminates the need for multiple contractors saving time and money. One appointment can include all separate surveys.

It is often the case that a basic survey (i.e. pre-purchase), can restrict our findings due to lack of access. This can hinder our diagnosis and treatment.

In most cases, we can provide a specialist invasive survey which can involve removing part of the fabric of the building to give us more access.

This is a well requested survey that can pinpoint areas of unwanted moisture that others have missed, saving any unnecessary expensive treatments.

Our surveys use the latest diagnostic tools and equipment and are all conducted in house by our surveyor.

Our reports are written up usually within 48 hours of the site survey and are in laymen’s terms for easy understanding.

What our customers say...

Very professional


"Contacted Preservatech about some damp in a bedroom, from first contact until completion Dave was very professional, you can tell he has so much experience and knowledge in his field, he really knows his stuff and it shows. Very friendly and always available to take time to answer any of our questions about the work keeping us updated throughout.

Super happy with the work done and the clean up afterwards was better than expected, so clean and tidy. Wouldn't hesitate to recommend him to anyone needing a reliable and trusted tradesman. Thank you!"




Natalie De Biase

Quality of work was exceptional


"Can’t speak more highly of Dave at Preservatech. I discovered rotten joists connecting to my stone fireplace half which were preventing the installation of my log burner.


Within a day of speaking to Dave, he had called into my house to diagnose then problem and sent me an estimate through later that day.

The quality of work was exceptional, and the straight forward approach from quote to completion made the whole experience stress free"
