Why it’s worth doing now in North Holmwood
If you’re redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. In an older home around North Holmwood, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
When something else is needed
We’d rather tell you now than do work that won’t last, so these are the limits:
- Masonry that needs repairing
- Decisions on consent for listed homes
- Sashes that rattle, stick or will not open
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before you book.

The process
The work is kept neat and contained to the joints we’re treating. The job usually takes a few hours per window, depending on the condition of the joints. In a smaller place like North Holmwood, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
