Window Mastic in Kennethmont
We cover Kennethmont for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Gaps between the frame and the inside reveal
- Water coming in at the bottom corners of a door
- Leaking joints at the ends of sills
Why it’s worth doing now in Kennethmont
Resealing frames is a short job: it takes a few hours for a few frames, or a day or more for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Window mastic in Kennethmont
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you are dealing with rain getting in at the frame or under the sill and rushed sealant from a window installation, we can put it right, whatever the surface.
Mastic can only go onto a dry joint, so outside work in Kennethmont depends on the weather. Let us know about access to every frame, including any upstairs.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Common questions in Kennethmont
Is Kennethmont in your area for window mastic?
Yes. We work across all of Scotland, and Kennethmont is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Is Kennethmont within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is the new sealant paintable?
It depends on the sealant. Some hybrid sealants can be painted; silicone cannot. Tell us if you’re decorating and we will choose accordingly.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
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.
Can you reach windows above the ground floor?
Yes, if safe access is possible. For high or awkward windows, we will tell you what access is needed.
When it is not the sealant
We will always be straight with you, so here’s what sealant cannot fix:
- Damp coming through the wall itself rather than the frame joint
- Soft or decayed wood in the frame
- Broken hinges, locks or handles
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.
What we seal
- uPVC windows
- Composite doors
- Aluminium frames
- Window sills
- Timber windows & doors
- Patio & French doors
Surface by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep paint off silicone joints
- Use gentle cleaners on frames and sealant
- Ventilate rooms so frames don’t stay wet inside
- Walk round the house once a year and look at the joints
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
How the visit works
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours for a few frames, or a day or more for a whole house, including the tidy-up. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We start by checking each window and door with you.
- 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.
- Finally we tidy up and check each joint.
How to prepare
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height

What else we do in Kennethmont
Landlord and commercial work in Kennethmont
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
Do you need window mastic in Kennethmont?
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, and it lets go sooner than it should.
If you can see any of these, it’s time to have the joints looked at:
- White mastic on grey or black frames
- Whistling draughts around closed windows
- Gaps left after new windows were fitted
- Black, perished sealant on frames
Rented homes near Insch station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Windows and doors in Kennethmont
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. With historic houses such as Leith Hall (about 0.9 miles north-west) nearby, there’s older building stock in the area around Kennethmont 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.
Homes close to Kennethmont Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
