Window mastic in Shenington
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. Common call-outs are for leaking joints at the ends of sills and old mastic that has gone black or come away, on timber windows & doors, aluminium frames and uPVC windows.
Mastic can only go onto a dry, clean joint, so window work in Shenington is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Your job is guaranteed for a year, as with all our work.

The process
The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job normally takes most of a day for a typical house, less for a few frames, and we explain the cure time before we leave. In a small place like Shenington, 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.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.

Window mastic in Shenington: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Upton House (about 1.9 miles north) are a reminder that the area around Shenington has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Shenington Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of Holy Trinity, the joint between an old wall and a newer frame is usually the first place rain gets in.

When it isn’t the sealant
It helps to know what we cannot do too:
- A frame that has rotted at the joint
- Draughts through the window seals rather than the frame
- Damp problems in the wall away from the window
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.
Surfaces we seal
- Aluminium frames
- Composite doors
- Patio & French doors
- Timber windows & doors
- uPVC windows
- Window sills
How the job changes by surface
Composite doors
A composite door normally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it without cracking.
Why act early in Shenington
The work is quick compared with the damage it prevents: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. In a small place like Shenington, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
