How we handle sand mastic in Dalchalm
Sand mastic suits most period window surrounds. Newer frames usually get a flexible sealant instead and we’ll explain which is best for yours. Typical jobs include wind and rain getting in round a sash window and crumbling sand mastic round a window, on timber door frames, brick reveals and stone surrounds.
Outdoor sealant needs a dry surface, so window work around Dalchalm is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
All our work is covered by a one-year guarantee, wherever you are in Highland.

Dalchalm: your questions answered
Do you work for landlords with property near Brora station?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. 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 sand mastic in a coastal place like Dalchalm any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
What is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- How easy the joints are to reach
- How many areas need sealing
- The amount of work
- Mould in or behind the old joints
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Asking for a quote

- A few pictures by email, if you can

Dalchalm homes and the weather
Dalchalm is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
In and around Dalchalm, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It usually takes a few hours for a single window, longer for several. Outside jobs in Dalchalm need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks

Why act early in Dalchalm
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why choose Mr Mastic in Dalchalm

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Avoid heavy scraping on the mastic joint
- Leave the new mastic unpainted
- Check the mastic when you check the paintwork
- Plan mastic work ahead of painting
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
