The Offer

We will supply whatever cills will be required for your Kastrup windows free of charge

The vast majority of windows we install need window cills. The cills have an aesthetic benifit,covering the gap under the window and  improving the appearance of the bottom of the window. But more importanly, they protect the lower part of the opening from the elements.

The cost of the cills is normally included in our quotes. Under this offer, your quote will itemise the cost of the cills and the amount of the quote will be lowered by that amount.

The value of the cills will vary depending on the quote but can be as much as £2000.
