Gellyburn Window Mastic
Mastic around window and door frames, sills and patio doors for householders, landlords and businesses in Gellyburn. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.

When to call us in Gellyburn
Sun, frost and rain wear sealant out. Sunlight dries the surface out, until it loses its stretch and starts to crack.
Look out for any of the following:
- Gaps left after new windows were fitted
- Cracked or shrunken mastic around the frame
- Rain getting in at the frame or under the sill
- Gaps between the frame and the inside reveal
Rented homes near Dunkeld & Birnam station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before booking
- Are they insured?
- How much experience the applicator has
- How the colour is chosen
- What the cure time is
Window mastic in Gellyburn
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you are dealing with damp patches on the reveal after heavy rain and gaps where the sill meets the wall, we can help.
Outdoor sealant needs a dry surface, so window work around Gellyburn is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
Your job is guaranteed for a year, as with all our work.

What the job involves on each surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it, where a rigid one would crack.
Gellyburn homes and the weather
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Homes close to Caputh Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How it works

Expect the work to take anything from an hour or two to a full day, depending on how many frames there are, and we tell you how long to leave it before we go. Outdoor work around Gellyburn depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.

Advice
FAQs for Gellyburn
I let a flat near Dunkeld & Birnam station. Can you help?
Yes. We work for landlords and agents as well as householders. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Is Gellyburn in your area for window mastic?
Yes, Gellyburn is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Are you insured?
Yes. Mr Mastic is fully insured.
Is the new sealant paintable?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Mention any painting plans before any work starts.
Can I do it myself?
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.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Do you work on first-floor windows?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we will confirm what’s needed.
What affects the cost of window mastic
Your quote is based on your job. We take into account:
- The amount of work
- Whether there’s mould to deal with
- How many areas need sealing
- How easy the joints are to reach
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Helping us quote
What to tell us when you ask for a quote:
- Any previous sealing or DIY work
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
There’s no standard price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, send an email to info@mrmastic.co.uk.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Keep solvents and bleach off the sealant
- Keep paint and stain on wooden frames in good order
- Use gentle cleaners on frames and sealant
- Clear any debris from frame drain holes
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
Leave it or put it right?
The work is quick compared with the damage it prevents: it takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.
