Window mastic in Olney, done properly
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. Just phone 0345 464 0079 or send us an email and tell us how many frames there are and how they’re reached for window mastic in Olney. We work on aluminium frames, uPVC windows and composite doors, and common reasons people get in touch are draughty joints inside around the window and untidy mastic left by window fitters.
In smaller places like Olney, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
Whatever the size of the job, you get the same 12-month guarantee in Olney and across Milton Keynes.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Honest limits
Before booking, it’s worth knowing the limits too:
- Damp problems in the wall away from the window
- A sash or casement that won’t close properly
- A failed sealed unit that has misted up
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
Surfaces we seal
- uPVC windows
- Timber windows & doors
- Patio & French doors
- Window sills
- Aluminium frames
- Composite doors
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Look round the frames every year or so
- Keep jet washers away from the mastic
- Repaint timber before it’s bare
- Wipe condensation off the frames
Keep the new mastic undisturbed while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.

Your questions about window mastic in Olney
Can you do window mastic in Olney?

Is there a guarantee on window mastic in Olney?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
How do I get a quote for window mastic in Olney?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you reach windows above the ground floor?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
Is the new sealant paintable?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Tell us if you are decorating and we will choose accordingly.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

What window mastic looks like in Olney
Historic houses like Turvey Abbey (about 3.7 miles east) are a reminder that the area around Olney has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Olney Middle School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of Saints Peter and Paul, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What happens if it’s left?
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. In an older home around Olney, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
