Window & door mastic in Bedgrove, Buckinghamshire
Problem with your window and door frames in Bedgrove? We remove the old material, prepare the joints and seal them properly.
- A bead that does not match the frame
- Leaking joints at the ends of sills
- Mastic that has split away from the wall
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
How we handle window mastic in Bedgrove
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. We work on composite doors, window sills and aluminium frames, and the jobs we see most are draughts coming in around windows and doors and mastic that’s falling out in pieces.
In a smaller place like Bedgrove, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

What we cannot put right
A few problems are outside what sealant work can do:
- A door that needs adjusting, rehanging or new seals
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Penetrating damp from a failed cavity tray or render

What we’re called out for in Bedgrove
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
The most common problems we see are:
- Draughts coming in around windows and doors
- Gaps where the sill meets the wall
- Untidy mastic left by window fitters
- Hard, cracked sealant around windows
For site and facilities teams at buildings such as Bedgrove Infant School, the mastic around its windows and doors needs looking after like any other building’s.

- What preparation is included

Frames and glazing around Bedgrove
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of the Holy Spirit, the joint between an old wall and a newer frame is usually the first place rain gets in. For landlords with property near Stoke Mandeville station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes most of a day for a typical house, less for a few frames and we leave things clean and tidy. A visit to Bedgrove is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children

Advice
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep solvents and bleach off the sealant
- Clean frames with a soft cloth and soapy water
- Keep timber frames painted
- Paint up to the joint, not over it
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.

Common questions in Bedgrove
Is Bedgrove within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Stoke Mandeville station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
How long does it take to reseal the windows on a house?
A few frames take a few hours. We confirm the timing with your quote.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can resealing stop a draught around my window?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly.
