St Cyrus homes and the weather
St Cyrus is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Homes close to St Cyrus Uf Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Window mastic in St Cyrus
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on window sills, composite doors and patio & French doors, and common reasons people get in touch are white mastic on grey or black frames and leaking joints at the ends of sills.
Outdoor sealant needs a dry surface, so window work around St Cyrus is planned around the weather. Let us know about access to every frame, including any upstairs.

Common problems we fix in St Cyrus
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
These are the problems we’re asked about most:
- Gaps between the frame and the inside reveal
- Water coming in at the bottom corners of a door
- Hard, cracked sealant around windows
- Mastic that is falling out in pieces
For landlords with property near Montrose station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

For landlords and businesses
If you manage several properties in or around St Cyrus, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
What the job involves on each surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Composite doors
A composite door usually sits in a plastic outer frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
What happens on the day
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a morning for a couple of windows and a door. Outdoor work around St Cyrus depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children

Advice
Aftercare tips
So the new joints stay in good condition:
- Do not use solvent cleaners on the joint
- Make sure the drainage slots are not blocked
- Keep paint and stain on wooden frames in good order
- Don’t 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.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
FAQs for St Cyrus
Is St Cyrus within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Does the coastal weather in St Cyrus affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Will resealing my frames help with draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Where do you work from?
We’re based in Crawley, and we work across South East England, London and Scotland.
What information do you need?
A short description and the location. We will ask anything else we need to know.
Why deal with it now?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. 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.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
