How many windows can you do in a day?
That depends on the number of frames, how they’re reached and the state of the old mastic. We will tell you how long your job needs when we quote.
Can you reach windows above the ground floor?
Yes, as long as they can be reached safely. Tell us about access when you get in touch so we can plan the job.
Can you seal the gap between the frame and the plaster indoors?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Do you have insurance?
Yes. We are fully insured.
About our window mastic in Shottermill
The new joint does not have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you have gaps between the frame and the inside reveal and cold air getting in at the frame edge, we can put it right, whatever the surface.
Many houses in smaller places like Shottermill have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
Whatever the size of the job, it’s backed by our 12-month guarantee.

The process
The work is kept neat and contained to the area we are working on. The job normally takes most of a day for a typical house, less for a few frames. For a job in Shottermill, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Tell us about any water getting in
- Move anything stored near the joints
- Keep children and pets away from the work area

What window mastic looks like in Shottermill
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.
For landlords with property near Haslemere station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like Camelsdale Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why deal with it now?
Running fresh sealant over the old joint is tempting, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. In an older home around Shottermill, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Signs you need window mastic in Shottermill
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Keep an eye out for any of the following:
- Rain getting in at the frame or under the sill
- Cracked or shrunken mastic around the frame
- Draughts coming in around windows and doors
- A bead that does not match the frame
In the older streets around St. Stephen's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
