Why act early in Strathy
The builder is normally the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. In an older home around Strathy, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
What you get with us
- We agree the colour with you first
- A 12-month guarantee on all work

New build mastic in Strathy, done properly
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. Common call-outs are for kitchen sealant that has pulled off the wall and plot mastic for developers ahead of handover, across windows & doors, skirting & floors and show homes.
For a place like Strathy, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
Your job is guaranteed for a year, as with all our work.

Landlords, agents and businesses in Strathy
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Letting agents and landlords in Strathy can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Record problems with dated photos
- Use the extractor fan every time you shower
- Don’t wait for the house to settle if water is getting through
- Follow the cure time we give you
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.
The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home. Outdoor work around Strathy 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 go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
How to prepare
- For business premises, tell us about site rules or sign-in
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky

Strathy: your questions answered
Will you come out to Strathy?
Yes, Strathy is covered. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is there a guarantee on new build mastic in Strathy?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
What new build mastic looks like in Strathy
Strathy is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. The west of Scotland is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.
Whether the job is in Strathy itself or nearby, the right material for each joint matters as much as a neat finish. In and around Strathy, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Strathy is about 17 miles west of Thurso, in Highland. We provide new build mastic to homes and businesses in Strathy and the surrounding area, as part of our work across Highland. Our Highland coverage runs to 253 places, Strathy among them.
Every address in KW14 is within our area for new build mastic, from the main roads to the quietest streets. We also cover the places around Strathy: Portskerra (3 miles east), Melvich (3 miles east), Reay (8 miles east), Am Blàran Odhar (8 miles west) and Forss (13 miles east). If you’re somewhere remote, the job takes a little more planning.
Local landmarks in Strathy
The countryside around Strathy includes Lochan Ealach.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What affects the quote in Strathy
The price is agreed before any work begins. It’s based on:
- Working hours on commercial sites
- Any mould that needs treating
- How much there is to do
- Whether the work is at height
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now
- Roughly how big the job is
