How we handle window mastic in Mursley
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you are dealing with gaps between the frame and the inside reveal and gaps where the sill meets the wall, we can help, on patio & French doors, aluminium frames and window sills alike.
Somewhere as small as Mursley, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
All our work is covered by a one-year guarantee, wherever you are in Milton Keynes.

Common questions in Mursley
I let a flat near Bletchley station. Can you help?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Is Mursley in your area for window mastic?
Yes. Our work covers London and the South East, and Mursley is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can I paint over the new sealant?
Silicone generally will not take paint. Let us know beforehand, and we’ll use a paintable product where it suits.
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’ll tell you how long your job needs when we quote.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
When something else is needed
To be straight with you, there are a few things sealant will not fix:
- Faulty window hardware
- A failed sealed unit that has misted up
- A door that needs adjusting, rehanging or new seals
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.

Windows and doors in Mursley
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Bletchley Park (about 4.5 miles north-east) nearby, there’s older building stock in the area around Mursley as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Bletchley station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Managing a site like Mursley Church of England School? Then its window and door frames need their mastic kept sound, just like a home’s.

How it works
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes anything from an hour or two to a full day, depending on how many frames there are in most cases. For a village or hamlet like Mursley, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints

Advice
What the job involves on each surface
Aluminium frames
Coated aluminium needs a compatible sealant. We use a neutral-cure product.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so they get particular care.
DIY sealant or a professional job?
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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
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. Proper resealing starts with removing the old joint. Older cottages and farmhouses around Mursley can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Why book with us
- White, clear, grey or another colour, product permitting
- An ARBOMaster approved applicator
- Domestic, commercial and hotel work
- Every job guaranteed for a year

Signs you need window mastic in Mursley
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. If the sealant can’t stretch, it splits.
Common reasons people contact us include:
- Cracked or shrunken mastic around the frame
- Old mastic that has gone black or come away
- Rushed sealant from a window installation
- Damp patches on the reveal after heavy rain
If you live in an older home near Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

- Who turns up on the day
- Is VAT in the price?
