Traditional burnt sand mastic around sash and case windows and doors in stone and brick for homeowners, landlords and businesses in Prestonfield. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.

- Mastic dropping out of the joint
- Wind and rain getting in round a sash window
Surface by surface
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.
Period and listed homes
Period homes look their best with traditional materials.
How we handle sand mastic in Prestonfield
Across Prestonfield, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. Common call-outs are for patchy fillers round a sash window and draughts and rain around sash boxes, on timber door frames, stone surrounds and period & listed homes.
Prestonfield is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Stone needs a sealant that suits it, which generally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

When to call us in Prestonfield
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
These are the problems we are asked about most:
- Open joints round the window box
- Draughts and rain around sash boxes
- Silicone on a period window that looks wrong
- Crumbling sand mastic round a window
For an older house near a landmark such as Priestfield Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Your questions about sand mastic in Prestonfield
Can you help a landlord with a rental near Edinburgh Waverley station?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
How do repairs to the shared parts of a tenement in Prestonfield get organised?
The owners of the flats generally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds do not. Your title deeds will say who owns the windows.
Should I use sand mastic or silicone?
That depends on your windows. Period windows in stone or brick usually suit sand mastic and newer frames usually get a flexible sealant.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Do you guarantee sand mastic work?
Our 12-month guarantee applies to all our work.
Can I choose the sealant colour?
Most of the time, yes. We will explain which colours are available.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Prestonfield homes and the weather
Prestonfield is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. With historic houses such as Whitefoord House (about 1.4 miles north-west) nearby, there’s older building stock in the area around Prestonfield as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For landlords with property near Edinburgh Waverley station, older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as St Margaret's School, its window and door frames need their mastic kept sound, just like a home’s.

Why it’s worth doing now in Prestonfield
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. For landlords in Prestonfield, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.

What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours per window, depending on the condition of the joints, and the area is left clean. Parking in city streets around Prestonfield can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
