About Us

Warm Wall was built around a simple principle: insulation should be done properly, and done once — with full consideration for the building and the people living in it.
Over the years we saw too many short-term fixes, rushed specifications and installations driven by price rather than long-term performance. Warm Wall was created to do the opposite — focusing on correct system choice, correct detailing and work that stands up over time.

We focus on the parts of insulation work that genuinely affect performance and durability. That means planning carefully, documenting each stage and finishing installations to a standard that will last. External wall insulation is never just about adding insulation boards — it is about how the system works with the entire building envelope, including window positions, junction detailing, existing coatings and how the final finish sits within the character of the property.

We work in a straightforward, practical way. We explain options clearly, outline what each system means for the building long-term, and help homeowners make informed decisions without pressure or sales-driven recommendations. Our approach is based on consistency, tidy installation standards and respect for the homes we work on.

Local Expertise

We work across Northamptonshire and the surrounding counties, where housing ranges from Victorian brick terraces to early blockwork homes and mixed‑construction extensions. These buildings behave differently depending on age, materials and exposure, so the EWI system has to be matched to the property rather than applied as a standard package.

Our experience with local housing stock helps us choose systems that suit older masonry, patched façades and varied substrates. By using complete certified systems from established UK manufacturers, we can adapt to different wall types while keeping both performance and appearance consistent.
