Our window mastic service in the Scottish Borders

Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. Typical jobs include draughty joints inside around the window and gaps where the sill meets the wall, across aluminium frames, uPVC windows and patio & French doors.

Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a handful of frames, longer for a whole house.

First we look at every frame and agree the list.
We remove the old mastic and clean the frame and the wall.
We fit backing rod in deep gaps so the sealant is the right depth.
We apply a weatherproof sealant to match the frame and tool it neatly.
Finally we tidy up and check each joint.

Local landmarks in Galashiels

In Galashiels, that means homes and buildings near Galashiels, Public House and Galashiels Academy and the streets around them. There’s a railway station in Galashiels itself: Galashiels station. Well-known places in the area include Borders General Hospital (2.7 miles south-east) and Castle Holydean (4.4 miles south-east). Not far away are Eildon Mid Hill.

Frames and weather across the Scottish Borders

Across the Scottish Borders, from Galashiels, Hawick and Peebles outwards, frames range from older timber to modern uPVC and aluminium. Each needs the right sealant, and every joint wears out eventually.

Scottish weather is hard on outside joints, especially in the wetter west. Sealants for jobs in the Scottish Borders are chosen with that in mind. Parts of the Scottish Borders are on or near the coast, where wind-driven rain and, closer to the shore, salt air are hard on outside sealant. Joints on seaward walls tend to fail first.

Galashiels: Rented homes near Galashiels station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Historic houses such as Peel House, about 3.8 miles west, show how far back building around Galashiels goes.

Work for landlords, hotels and businesses

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.

If you manage several properties in or around the Scottish Borders, several properties can be quoted together. Send us the addresses and the work at each, and pictures by email help.

Aftercare tips

No joint lasts for ever, but care makes a real difference. A few tips:

Clear any debris from frame drain holes
Keep paint and stain on wooden frames in good order
Walk round the house once a year and look at the joints
Avoid blasting the frames with a pressure washer

A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just email us at info@mrmastic.co.uk.

Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.

What we’re called out for in the Scottish Borders

Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.

Common reasons people contact us include:

Gaps left after new windows were fitted
White mastic on grey or black frames
Hard, cracked sealant around windows
Gaps where the sill meets the wall

Why act early?

Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint.

Questions to ask before booking

How the job changes by surface

Window sills

Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.

Patio & French doors

Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.

Questions from the Scottish Borders

Do you take out the old sealant first?

Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Do you guarantee window mastic?

Yes. Each job is covered for 12 months, inside or out.

Does someone need to be in?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Is it messy?

Tidy work is part of the job. Nearby surfaces are protected.

Is the new sealant paintable?

That depends on the product. Silicone isn’t paintable, but some hybrid sealants are. Mention any painting plans before work begins.

How long before the joint can be used?

That depends on the sealant used, so follow the cure time we give you.

What information do you need?

Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
