Window & door mastic in Wishanger Common, Surrey
Mastic around window and door frames, sills and patio doors for homeowners, landlords and businesses in Wishanger Common. Fully insured, ARBOMaster approved and guaranteed for a year.
- Gaps between the frame and the inside reveal
- Whistling draughts around closed windows
- Sealant in the wrong colour for the frame
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Window mastic in Wishanger Common
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. Where the air is getting in through the window itself, we’ll say so. We work on window sills, uPVC windows and timber windows & doors, and people most often call us about black, perished sealant on frames and sealant in the wrong colour for the frame.
Mastic can only go onto a dry, clean joint, so window work in Wishanger Common is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

When to call us in Wishanger Common
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
The most common problems we see are:
- Black, perished sealant on frames
- Cold air getting in at the frame edge
- Gaps between the frame and the inside reveal
- Hard, cracked sealant around windows
If you let a flat or house near Bentley (Hampshire) station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

- Whether VAT is included

Why it’s worth doing now in Wishanger Common
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Where a wall is exposed, as many are in small places like Wishanger Common, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why us?
- Neat joints and a tidy finish
- Trusted Arbo and Everbuild sealants
- We agree the colour with you first
- Approved under the ARBOMaster scheme

Windows and doors in Wishanger Common
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St John the Evangelist include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Use gentle cleaners on frames and sealant
- Paint up to the joint, not over it
- Check the mastic once a year
- Ventilate rooms so frames do not stay wet inside
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.

Different surfaces, different methods
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we’ll tell you before going ahead, as that’s a job for a joiner.
The process
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a few frames, or a day or more for a whole house, depending on the amount of work. In a small place like Wishanger Common, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Mention any tricky access
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky
