Customer reviews

Discover what our customers have to say

“Great service! The initial consultation with Roemer over the phone was very friendly. Afterwards, Youri visited us for an on-site consultation. We ultimately had our cavity wall and floor insulated at a very reasonable price, and they also helped us with the subsidy application. Definitely recommended if you’re starting to make your home more energy-efficient.”

Frequently asked questions

Questions we often receive

We’ve gathered the most common questions from our visitors and customers for your convenience.

A phone consultation with one of our advisors is always free. We provide a tailored preliminary recommendation for your home at no cost, using geo-data combined with your specific property details.

Insulation offers many advantages. One of the main reasons is the reduction of your energy bills. For example, cavity wall insulation can save up to 800 m³ of gas per year.

Improved comfort is another key benefit. Floor insulation, for instance, makes your floors noticeably warmer, contributing to a more comfortable indoor environment.

With rising energy prices, insulating your home is more beneficial than ever—helping your investment pay for itself even faster.

A cavity wall consists of two separate walls: an inner wall and an outer wall. The key feature of this construction is the hollow space between them—typically around 6 cm wide—known as the cavity.

During cavity wall insulation, this empty space is filled with insulation material to reduce heat loss and improve energy efficiency.

Yes, you may be eligible for a subsidy for your insulation or sustainability project. We’re happy to advise and support you in applying for available grants. Contact us for more information.

Improving your home’s sustainability boosts its energy label, which can increase its market value. A higher energy rating means lower energy costs and makes your property more attractive to buyers.
