Window mastic in Brookwood
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We work on composite doors, aluminium frames and patio & French doors, and common reasons people get in touch are mastic that has split away from the wall and rushed sealant from a window installation.
Outdoor sealant needs dry, clean surfaces, so work on frames around Brookwood is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Big or small, it’s backed by our one-year guarantee in Brookwood and across Surrey.

Can you seal the gap between the frame and the plaster indoors?

Can tenants book the work?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Can I paint over the new sealant?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Different surfaces, different methods
Aluminium frames
Coated aluminium needs a compatible sealant. We use a neutral-cure product.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that without cracking.
The process
We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes most of a day for a typical house, less for a few frames. In a small place like Brookwood, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints

London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Why act early in Brookwood
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Around Brookwood, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
