Window & door mastic in Amisfield, Dumfries and Galloway
Mastic around window and door frames, sills and patio doors for householders, landlords and businesses in Amisfield. Fully insured, ARBOMaster approved and guaranteed for a year.
- Cold air getting in at the frame edge
- Mastic that has split away from the wall
- Black, perished sealant on frames
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Do not paint over the silicone
- Wipe condensation off the frames
- Keep timber frames painted
- Keep drainage slots and sill grooves clear
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
Leaks normally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Window mastic for homes and businesses in Amisfield
Homes in Amisfield have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on window sills, patio & French doors and aluminium frames, and common reasons people get in touch are draughts coming in around windows and doors and old mastic that has gone black or come away.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes most of a day for a typical house, less for a few frames. Around Amisfield, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky
- Clear items away from the joints we are working on

Advice
Windows and doors in Amisfield
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. 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.
Homes close to Tinwald Parish Church include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

Why act early in Amisfield
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.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Do you need window mastic in Amisfield?
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Common reasons people contact us are:
- Untidy mastic left by window fitters
- Draughty joints inside around the window
- Mastic that has split away from the wall
- Rain getting in at the frame or under the sill
Letting a property close to Dumfries station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before booking
- Whether VAT is included
- Whether the sealant suits the joint
- Are they insured?

Landlord and commercial work in Amisfield
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
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.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How we quote for window mastic
The price is agreed before any work begins. It’s based on:
- The number of rooms or windows
- The old material and how stubborn it is
- Working hours on commercial sites
- The product the joint needs
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- A few photos by email, if you can
- What’s wrong with the joints now
- The address or postcode of the job
- How many joints, rooms or windows are involved
We don’t publish a price list, because every job is different. Instead, we give you a clear price for your job. To arrange one, send an email to info@mrmastic.co.uk.
