Window mastic in Tenston, done properly
Around Tenston we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on aluminium frames, patio & French doors and composite doors, and common reasons people get in touch are white mastic on grey or black frames and gaps where the sill meets the wall.
In and around a place like Tenston, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Surface by surface
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.
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. If we find rot, we will tell you before going ahead, as that is a job for a joiner.

Why act early in Tenston
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’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. In an older home around Tenston, damp from a failed joint can get into timber and plaster.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What happens on the day
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes a few hours for a handful of frames, longer for a whole house. For a place like Tenston, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children

Advice
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Clean frames with a soft cloth and soapy water
- Avoid harsh chemicals near the mastic
- Ventilate rooms so frames don’t stay wet inside
- Walk round the house once a year and look at the joints
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
Windows and doors in Tenston
Tenston is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Historic houses such as Skaill House, about 2.8 miles north-west, show how far back building around Tenston goes, and older homes nearby need a sealant that suits their walls. In and around Tenston, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Your questions about window mastic in Tenston
Is Tenston within the area you cover?
Yes, we do. Our work covers the whole of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
Does the coastal weather in Tenston affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Will resealing my frames help with draughts?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that is a different fix, and we will say so.
Can landlords and businesses book you?
Yes. We work for householders, landlords, letting agents, businesses and hotels across the Orkney Islands.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
