Questions from Swinton
Is window mastic in Swinton guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is Swinton within the area you cover?
Yes. Swinton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can resealing stop a draught around my window?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Do you work for landlords and businesses?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
Do you do commercial work?
Yes. We can plan bigger jobs in stages to suit the site.
Do you have insurance?
Yes, we’re fully insured for every job we do.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Window mastic in Swinton, done properly
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. Common call-outs are for mastic that has split away from the wall and rain getting in at the frame or under the sill, across timber windows & doors, window sills and uPVC windows.
In and around a place like Swinton, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
All our work is covered by our 12-month guarantee.

When it is not the sealant
Before you book, it’s worth knowing the limits:

More about window & door mastic
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Aftercare tips
After the cure time, these simple habits help:
- Keep jet washers away from the mastic
- Air rooms to keep condensation down around windows
- Do not use solvent cleaners on the joint
- Keep timber frames painted
Most silicone sealants won’t take paint, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
What window mastic looks like in Swinton
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Whether the job is in Swinton itself or nearby, the right material for each joint matters as much as a neat finish.

Surface by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Composite doors
A composite door usually sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
For landlords and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
What happens on the day
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Outside jobs in Swinton need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed

Advice
Do you need window mastic in Swinton?
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
Signs it’s time to call us include:
- Cracked or shrunken mastic around the frame
- Cold air getting in at the frame edge
- Damp patches on the reveal after heavy rain
- White mastic on grey or black frames
In and around Swinton, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
