Window mastic in Drayton Parslow
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We’re often asked to deal with black, perished sealant on frames and white mastic on grey or black frames, on patio & French doors, uPVC windows and timber windows & doors.
In a village or hamlet like Drayton Parslow, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Drayton Parslow questions
Do you cover Drayton Parslow for window mastic?
Yes, Drayton Parslow 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.
I let a flat near Bletchley station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Can you do upstairs windows?
Usually, yes. We plan safe access before the job.
How do I get a quote for window mastic in Drayton Parslow?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Do you guarantee window mastic?
Yes. All our work carries a 12-month guarantee, and we’re fully insured.
Can I paint over the new sealant?
Not generally, if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Surface by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a morning for a couple of windows and a door. Somewhere like Drayton Parslow needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints

Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, ring 0345 464 0079 or drop us an email.

What else we do in Drayton Parslow
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Don’t aim a pressure washer at the joints
- Use gentle cleaners on frames and sealant
- Walk round the house once a year and look at the joints
- Keep solvents and bleach off the sealant
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Why act early in Drayton Parslow
The work is quick compared with the damage it prevents: it takes most of a day for a typical house, less for a few frames. Leave it until water is coming in and you may need plastering and decorating as well. Where a wall is exposed, as many are in small places like Drayton Parslow, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Instead of a standard rate, 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.
What you get with us
- Arbo and Everbuild products
- Every job guaranteed for a year
- Colour agreed with you before work begins
- ARBOMaster approved applicator

Windows and doors in Drayton Parslow
With historic houses such as Bletchley Park (about 3.7 miles north-east) nearby, there’s older building stock in the area around Drayton Parslow as well as newer homes. Where a home is older, 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.
For an older house near a landmark such as Church of Holy Trinity, the joint between an old wall and a newer frame is usually the first place rain gets in. Rented homes near Bletchley station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Drayton Parslow Village School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
