Colchester's Leading Air Tightness Testing Specialists

First class, professional and highly accurate SAP calculation and air pressure testing solutions for clients across Colchester and Essex.

If you've recently undertaken an extension or new build project, you'll have likely come across companies offering you a 'takeaway' Building Regulation L1A compliance service. While they promise the earth and focus on cheap SAP calculations and air pressure testing, all they actually do is deliver costly and weak solutions that then require you to spend thousands of pounds on additional insulation or solar panels. You could easily avoid these additional costs by simply hiring a company with far more expertise and responsibility.

That's where Colchester's experts at Tophouse Assessments come in.

Working across Colchester and Essex for designers, builders and architects, we quote competitive and fair prices that enable us to craft and design the highest quality and most accurate SAP calculations and air leakage testing solutions for our clients. Boasting many decades of unrivalled experience and expertise, we offer each and every client the most affordable and cost effective ways of meeting all current Building Regulations for conversions, highly glazed extensions or new builds. 

As one of Colchester and Essex's leading air tightness, air pressure and air leakage testing specialists, we will provide you with the highest quality compliance services that are optimised and designed to reduce your build costs and allow you to build better and more energy efficient properties throughout Colchester, Essex and the surrounding area. Call Tophouse Assessments today on 01634 799115.
