Window & door mastic in Stratherrick, Highland
Mastic around window and door frames, sills and patio doors for householders, landlords and businesses in Stratherrick. Fully insured, ARBOMaster approved and guaranteed for a year.

- Cracked sealant at the sill ends
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again.
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.
Window mastic for homes and businesses in Stratherrick
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. Common call-outs are for white mastic on grey or black frames and leaking joints at the ends of sills, on composite doors, uPVC windows and aluminium frames.
In and around a place like Stratherrick, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Frames and glazing around Stratherrick
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For jobs in and around Stratherrick, choosing the right material for each joint is as important as a tidy finish.
Stratherrick is about 22 miles south-west of Inverness, in Highland. Across the IV2 area, we cover window mastic for homes and businesses. Our Highland coverage runs to 253 places, and Stratherrick is one of them. We also work in Dundee, about 77 miles from Stratherrick.
Work in IV2 is quoted and booked the same way as anywhere else. If you are just outside Stratherrick, we cover Invermoriston (4 miles north-west), Gorthleck (5 miles north-east), Fort Augustus (7 miles south-west), Newtown (9 miles south-west) and Lewiston (10 miles north). If you are somewhere remote, a little more planning is needed.

Why it’s worth doing now in Stratherrick
Running fresh sealant over the old joint is tempting, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. In an older home around Stratherrick, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What you get with us
- Colour agreed with you before we start
- Arbo and Everbuild products
- White, clear, grey or coloured to suit, where the product allows
- Anti-fungal sanitary silicone in wet areas
Keeping the joints in good condition
So the new joints stay in good condition:
- Ventilate rooms so frames don’t stay wet inside
- Make sure the drainage slots aren’t blocked
- Keep paint and stain on wooden frames in good order
- Do not paint over the silicone
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.

What else we do in Stratherrick
Do you need window mastic in Stratherrick?
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
If you can see any of these, it’s time to have the joints looked at:
- Rain getting in at the frame or under the sill
- Untidy mastic left by window fitters
- Leaking joints at the ends of sills
- A bead that does not match the frame
In and around Stratherrick, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Stratherrick questions
Is Stratherrick within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
What guarantee comes with window mastic in Stratherrick?
All our work, in Stratherrick and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you work for landlords and businesses?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Honest limits
It helps to know what we can’t do too:
- Broken hinges, locks or handles
- Condensation trapped between the panes
- Rotten timber, which needs a joiner first
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
What we seal
- Window sills
- Patio & French doors
- Composite doors
- Timber windows & doors
- uPVC windows
- Aluminium frames
What happens on the day
We keep the work tidy and contained to the joints we are treating. Expect the work to take most of a day for a typical house, less for a few frames, and we explain the cure time before we leave. Outside jobs in Stratherrick need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
