Southend's Air Tightness Testing Specialists

Specialising in reliable, accurate, proven and honest air tightness testing and SAP calculations across Southend and Essex. 

There are a number of companies based in Southend and Essex that will offer you what we call a 'takeaway' Building Regulation L1A compliance service that focuses on cheap air leakage testing and SAP calculations. However, they consistently deliver weak and costly solutions that then require thousands of pounds to be spent on solar panels or extra insulation. With a little more expertise and experience, these additional costs could have been easily avoided.

That is exactly where Tophouse Assessments come in.

Working for a variety of architects, property designers and builders across Southend and Essex, we quote fair and competitive prices that give us the very best opportunity to craft and design the most accurate SAP calculations and air pressure testing solutions for our Southend clients. Utilising our decades of expertise, we will explore the most cost effective ways of helping you meet all current Building Regulations for your extensions, new builds or conversions. 

As Southend's most trusted and respected air pressure testing specialists, we will provide you with the very best building regulation compliance services that are optimised to reduce your build costs and enable you to build better homes throughout Essex. Call Tophouse Assessments today on 01634 799115.
