How we handle window mastic in Dolphinton
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. Where the air is getting in through the window itself, we’ll say so. If you are dealing with a bead that doesn’t match the frame and damp patches on the reveal after heavy rain, we can put it right, on aluminium frames, timber windows & doors and window sills alike.
In and around a place like Dolphinton, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

How we quote for window mastic
Every job gets its own quote. These are the things that affect it:
- The number of rooms or windows
- Any working-time requirements on site
- Mould in or behind the old joints
- How much there is to do
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
What we need to know
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we will explain what’s involved before giving you a price.
The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from an hour or two to a full day, depending on how many frames there are. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- Each frame is looked over and we agree which ones need resealing.
- 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.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints

Advice
What window mastic looks like in Dolphinton
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
For an older house near a landmark such as Dolphinton Parish Church And Churchyard, the joint between an old wall and a newer frame is normally the first place rain gets in.

Why it’s worth doing now in Dolphinton
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear quote before any work starts.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Signs you need window mastic in Dolphinton
Mastic ages in the weather. Sunlight dries the surface out, until it loses its stretch and starts to crack.
It’s worth asking for a quote if you see:
- Leaking joints at the ends of sills
- Rain getting in at the frame or under the sill
- Whistling draughts around closed windows
- Sealant in the wrong colour for the frame
In and around Dolphinton, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
