DIY sealant or a professional job?
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Window mastic in Lamlash
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. If you have untidy mastic left by window fitters and a bead that doesn’t match the frame, we can put it right, on aluminium frames, composite doors and uPVC windows alike.
Mastic can only go onto a dry joint, so outside work in Lamlash depends on the weather. Let us know about access to every frame, including any upstairs.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

How the visit works
At the end, we look at the finished work together. The visit itself usually takes anything from an hour or two to a full day, depending on how many frames there are, depending on the amount of work. Around Lamlash, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Clear items away from the joints we are working on
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions

Why act early in Lamlash
If you’re painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Around Lamlash, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Doing several joints on one visit is generally more efficient than separate visits. You’ll get one clear quote for the whole job.

What window mastic looks like in Lamlash
Lamlash is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. The west of Scotland is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
In and around Lamlash, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
Lamlash is about 15 miles south-west of Saltcoats, in North Ayrshire.

Signs you need window mastic in Lamlash
Older frames were often sealed with products that set hard. 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:
- Draughts coming in around windows and doors
- Sealant in the wrong colour for the frame
- Gaps between the frame and the inside reveal
- Cracked sealant at the sill ends
For site and facilities teams at buildings such as Arran High School, the mastic around its windows and doors needs looking after like any other building’s.

Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Draughts through the window seals rather than the frame
- Faulty window hardware
- Penetrating damp from a failed cavity tray or render

FAQs for Lamlash
Is Lamlash within the area you cover?
Yes. Lamlash is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is window mastic in a coastal place like Lamlash any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can resealing stop a draught around my window?
In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
What information do you need?
Let us know what needs doing and where, plus photos if you have them. We will ask anything else we need to know.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
