Chatham's Leading Air Tightness Testing Specialists

Proven, accurate and first class air pressure testing and SAP calculations for clients across Chatham and Medway. 

While there are many companies in the industry that offer a 'takeaway' Building Regulation L1a compliance service that focuses on cheap air leakage testing and SAP calculations, these consistently deliver costly and weak solutions that then require thousands of pounds spent on extra insulation or solar panels. These additional costs could easily have been avoided with more expertise; which is where Tophouse Assessments comes in.

Working for designers, architects and builders across Medway and Chatham, we quote competitive and fair prices that allow us to design and craft the most accurate and highest quality SAP calculations and air tightness testing solutions. Boasting extensive expertise and experience, we will explore the most effective ways of enabling you to meet all current Building Regulations for your conversions, new builds and extensions. 

As one of Chatham and Medway's leading air leakage testing companies, we will provide you with the very best compliance services that are optimised to reduce your build costs and enable you to build better homes throughout the region. Call Tophouse Assessments today on 01634 799115.
