Different surfaces, different methods
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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.

Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Will resealing my frames help with draughts?
Yes, if the air is getting in around the frame. If it’s coming through the window seals, we’ll tell you.
Do you have sealant for grey or black windows?
Yes, in most cases. Mention the frame colour when you ask for a quote and we will use the nearest match.
Can new window sealant be painted?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How many windows can you do in a day?
It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.
Why it’s worth doing now in Dechmont
Resealing frames is a short job: it takes a morning for a couple of windows and a door. Wait for damp to appear and there may be plaster and decorating to sort out too. 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.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

What we are called out for in Dechmont
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
The problems people normally mention when they call include:
- Mastic that has split away from the wall
- A bead that doesn’t match the frame
- Water coming in at the bottom corners of a door
- Old mastic that has gone black or come away
If you let a flat or house near Uphall station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before you book
- What the cure time is
- Which sealant they’ll use, and why
- How hidden problems are handled
- How the joint is cleaned and prepared
What affects the quote in Dechmont
Every job gets its own quote. This is what makes a difference:
- The product the joint needs
- How easy the joints are to reach
- When we can work, for business premises
- Any mould that needs treating
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
- The problem you’ve noticed
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work before giving you a price.
Frames and glazing around Dechmont
Historic houses like Howden House (about 2.1 miles south) are a reminder that the area around Dechmont has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
For an older house near a landmark such as Former Memorial Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Deans Community High School, the mastic around its windows and doors needs looking after like any other building’s.

Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- 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.
