Aftercare tips
So the new joints stay in good condition:
- Do not paint over the silicone
- Avoid blasting the frames with a pressure washer
- Walk round the house once a year and look at the joints
- Air rooms to keep condensation down around windows
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Where a wall is exposed, as many are in small places like Pirbright, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us and we will talk you through it.

What we do, step by step

Most jobs then take anything from an hour or two to a full day, depending on how many frames there are. In a small place like Pirbright, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.

What we’re called out for in Pirbright
Mastic ages in the weather. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Any of these means the joints need attention:
- A bead that doesn’t match the frame
- Whistling draughts around closed windows
- Rushed sealant from a window installation
- Hard, cracked sealant around windows
For landlords with property near Brookwood station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Windows and doors in Pirbright
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Wanborough Manor (about 4.4 miles south) nearby, there’s older building stock in the area around Pirbright as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For site and facilities teams at buildings such as Knowl Hill School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Michael and All Angels include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
