- Mastic that has split away from the wall
Why deal with it now?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

Window mastic in Lochgilphead, done properly
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. 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 window sills, composite doors and patio & French doors.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
We stand behind the work with a 12-month guarantee.

How it works
There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes most of a day for a typical house, less for a few frames, including the tidy-up. Somewhere like Lochgilphead may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height

Advice
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Different surfaces, different methods
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.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Honest limits
We will always be straight with you, so here’s what sealant can’t fix:
- Draughts through the window seals rather than the frame
- A failed sealed unit that has misted up
- Broken hinges, locks or handles
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

Your questions about window mastic in Lochgilphead
Does living near the coast affect window mastic in Lochgilphead?

Can resealing stop a draught around my window?
It will if the frame joint is the problem. We check where the draught is before any work starts.
Are you insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.

Windows and doors in Lochgilphead
Lochgilphead is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
If you live in an older home near Christ Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Lochgilphead High School? Then larger buildings have plenty of frames, and the mastic around each one ages.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Wipe condensation off the frames
- Use gentle cleaners on frames and sealant
- Keep jet washers away from the mastic
- Clear any debris from frame drain holes
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
