What affects the quote in Hourston
Call for a quick quote. What matters most is:
- The size of the job
- How easy the joints are to reach
- Mould in or behind the old joints
- Which sealant suits the joint
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:

- The rough size of the job
- Where the property is
- Access, such as stairs, a lift or height
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
Hourston homes and the weather
Hourston 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. Island weather, with its wind and salt spray, is tough on the mastic around older windows and doors.

Your questions about sand mastic in Hourston
Do you cover smaller places like Hourston?
Yes. Hourston is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.

Yes, Hourston is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Is there any odour?

Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
How long will you be here?
Most jobs take anything from a few hours to a full day, depending on how many windows, including preparation and clearing up. Your quote will say how long we expect yours to take.

Signs you need sand mastic in Hourston
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
If you can see any of these, it’s time to have the joints looked at:
- Mastic worn away on windows facing the weather
- Modern sealant on a period surround
- Cracked mastic round a front door frame
- Gaps between timber frames and stone or brick
In and around Hourston, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours per window, depending on the condition of the joints. Somewhere like Hourston may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Mention if the joints have been sealed before
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises

Advice
Leave it or put it right?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. In an older home around Hourston, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
