Dartford's Very Best Air Tightness Testing Specialists

Working across Dartford and Kent, we specialise in helping contractors, architects, building companies, designers and property builders to meet Building Regulation L1a for new homes and properties.

You may have seen some companies offering a 'takeaway' Building Regulation L1a compliance service that focuses on and provides cheap air leakage testing and SAP calculations. However, they deliver weak and potentially costly solutions that then require thousands of pounds unnecessarily spent on extra insulation or solar panels. These could all be avoided with more expertise, which is where Dartford's experts at Tophouse Assessments comes in.

Working for clients throughout Dartford and Kent, we design and craft the very best and most successful air leakage testing and SAP calculation regimes for very fair prices. Utilising our extensive air pressure testing experience in the industry, we explore the most effective and reliable ways of enabling you to meet building regulations for your extensions, new builds and conversions.

We want to provide you with the best compliance services optimised to reduce your build costs ‐ and still enable you to build better homes across Kent and Dartford. Put your future builds in our expert hands. Call Tophouse Assessments today on 01634 799115.
