Why KMS Inspects Every Loft Insulation Job 2 Months After Installation
Most insulation companies fit and forget. KMS sends a qualified assessor back to every single job 2 months later to inspect the work. Here's why that matters.

All Seasons Foil™ Insulation

If you've had loft insulation installed — whether it was last month or last year — how do you know it's actually doing its job? Most insulation companies fit it and disappear. You're left hoping the work was done properly, with no way of checking until your energy bill tells you otherwise.
At KMS Insulations, we do things differently. Every installation we carry out includes a 2-month post-install quality inspection — and it's one of the main reasons UK homeowners choose us over other installers.
What Is a Post-Install Quality Inspection?
Two months after your insulation is fitted, a KMS quality assessor returns to your property to carry out a full inspection of the installation. This isn't a phone call or an email check-in — it's a physical visit to your home where our assessor gets into your loft and checks every detail of the work.
They're looking at whether the insulation is still seated correctly, whether any areas have shifted or compressed, whether there's any sign of condensation or moisture ingress, and whether the overall finish is performing to the standard we promised when we booked the job in.
Why 2 Months?
Two months is long enough for any issues to emerge. If insulation is going to shift, sag, or develop moisture problems, it'll typically show within the first few weeks of being installed — especially through seasonal temperature changes. By inspecting at the 2-month mark, we catch anything that needs attention before it becomes a bigger problem.
It also gives you time to feel the difference in your home. By the time our assessor visits, you'll have had two full months of living with the new insulation and will know firsthand whether your home feels warmer and your bills have dropped.
What Happens If Something Isn't Right?
If our assessor finds anything that doesn't meet our standard, we fix it — at no extra cost. That might mean re-securing a section of foil, topping up an area that's compressed, or addressing a ventilation point that needs adjusting. Whatever it takes to get the installation to the level we expect from every KMS job.
This is backed by the 25-year manufacturer guarantee on All Seasons Foil, so you're covered both by KMS and by the product manufacturer for the long term.
Why Don't Other Companies Do This?
Honestly? Because it costs time and money. Sending a qualified assessor back to every single job two months later is an overhead that most insulation companies aren't willing to absorb. But at KMS, we see it as the foundation of our reputation. We're not interested in fitting insulation and hoping for the best — we want to know that every job we complete is performing exactly as it should.
It's also how we maintain our 100% client satisfaction rate. When you inspect every job, you catch problems before the customer even notices them. That's the kind of aftercare that builds trust.
