Sand Mastic in Longhope
We cover Longhope for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly.
- A silicone bead on a sash window that spoils the look
- Wind and rain getting in round a sash window
- Mastic that needs renewing before redecorating
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid patching sand mastic with silicone
- Clear gutters so water does not pour onto the windows
- Inspect the joints round the windows every year or so
- Find out about consent before window work on a listed home
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Sand mastic for homes and businesses in Longhope
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. If you are dealing with failed mastic on an exposed elevation and draughty sash windows at the surround, we can help, whatever the surface.
Outdoor sealant needs a dry surface, so window work around Longhope is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Whatever the size of the job, you get the same 12-month guarantee.

Windows and doors in Longhope
Longhope is within about 1 mile of 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. Island weather, with its wind and salt spray, is tough on the mastic around older windows and doors.
In and around Longhope, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Longhope: your questions answered
Does the coastal weather in Longhope affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.
Do you cover Longhope for sand mastic?
Yes. Our work covers the whole of Scotland, and Longhope is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
How long does sand mastic take to go off?
Not right away. It skins first and hardens fully later and we will give you an idea for your job.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What guarantee comes with the work?
Our 12-month guarantee applies to all our work.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Where do you work from?
We work from Crawley. We cover Longhope and the rest of the Orkney Islands, along with the rest of our area.
Do you need sand mastic in Longhope?
Most of it is simply age. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
These are the problems we are asked about most:
- Gaps round a timber door in stone or brick
- Gaps between timber frames and stone or brick
- Tired mastic found when preparing windows for paint
- Old sand mastic that has cracked, crumbled or fallen out
Whether the job is in Longhope itself or nearby, the right material for each joint matters as much as a neat finish.

Surface by surface
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
Brick reveals
Loose mastic comes out and deep gaps are packed before pointing.
What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours per window, depending on the condition of the joints. For a place like Longhope, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions

Why deal with it now?
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and give you a clear price before any work starts.
