Mastic around window and door frames, sills and patio doors for Loaningfoot, backed by a one-year guarantee. Ask us for a quote.
- Gaps where the sill meets the wall
- Cold air getting in at the frame edge
- Hard, cracked sealant around windows
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Keep solvents and bleach off the sealant
- Check the mastic once a year
- Keep paint off silicone joints
- Keep timber frames painted
A yearly look round the frames is enough. Small splits are simple to catch before they leak.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
How we handle window mastic in Loaningfoot
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are ARBOMaster approved and fully insured, and we give a 12-month guarantee on the work. We’re often asked to deal with hard, cracked sealant around windows and cracked sealant at the sill ends, on timber windows & doors, aluminium frames and composite doors.
Mastic can only go onto a dry joint, so outside work in Loaningfoot depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Big or small, it’s backed by our one-year guarantee in Loaningfoot and across Dumfries and Galloway.

Should I try it myself first?
If you are set on DIY, put the effort into 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.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
FAQs for Loaningfoot
Will you come out to Loaningfoot?
Yes. Loaningfoot is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Dumfries station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames usually suit brown.
How do I get a quote for window mastic in Loaningfoot?
Every job is different, so each one gets its own quote. To get one, email us at info@mrmastic.co.uk with a short description of the job.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Do you guarantee window mastic?
Yes. Every job comes with our one-year guarantee, and we are ARBOMaster approved applicators.
What the job involves on each surface
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We will tell you if that is what we find.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
What we’re called out for in Loaningfoot
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
Common reasons people contact us are:
- Gaps between the frame and the inside reveal
- Leaking joints at the ends of sills
- Untidy mastic left by window fitters
- Water coming in at the bottom corners of a door
If you look after a building such as Dumfries High School, its window and door frames need their mastic kept sound, just like a home’s.

Loaningfoot homes and the weather
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Rented homes near Dumfries station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Why act early in Loaningfoot
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we’ll say so. In a place like Loaningfoot, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
The cost depends on the size of the job, 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.
What you get with us
- More than 20 years in sealant work
