Window mastic in Stoke Poges
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. We are often asked to deal with gaps where the sill meets the wall and gaps left after new windows were fitted, on uPVC windows, timber windows & doors and composite doors.
Houses in smaller places like Stoke Poges can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
Your job is guaranteed for a year, as with all our work.

When to call us in Stoke Poges
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Keep an eye out for any of the following:
- A bead that does not match the frame
- Cracked sealant at the sill ends
- Untidy mastic left by window fitters
- Water coming in at the bottom corners of a door
Schools such as The Stoke Poges School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Windows and doors in Stoke Poges
With historic houses such as Windsor Castle (about 4.3 miles south) nearby, there’s older building stock in the area around Stoke Poges as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
Rented homes near Slough station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as St Andrew's Church Centre, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of frames, longer for a whole house. Parking around Stoke Poges is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Clear items away from the joints we’re working on
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Around Stoke Poges, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

What the job involves on each surface
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain cannot run into the wall.
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.

Stoke Poges questions
Will you come out to Stoke Poges?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Stoke Poges for window mastic?
Yes, Stoke Poges is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Will resealing my frames help with draughts?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that is a different fix, and we will say so.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
