Mastic sealing in Clestrain
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. We work on communal entrances and stairwells, window and door perimeters on blocks and shopfronts below residential blocks, and what we’re called in for most is communal area joints that look neglected and draughts at frames across a block. Facilities teams, main contractors and managing agents in Clestrain tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Travel to smaller places like Clestrain is planned so several buildings can be done on one trip. Send addresses and photos for a quote covering the batch.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Advice
What else we do in Clestrain
Owners, agents and contractors
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
What sets the cost
Each job is priced on its own details. The things that drive the figure:
- How much there is to seal
- The size and state of each joint
- The site’s rules and procedures
- Distance, for remote addresses
Pricing mastic joints depends on quantities, condition and access. Call for a quote.
What to include in your enquiry
The more we know, the firmer the quote. When you get in touch, include:
- The postcode of the building
- How the joints are reached, and at what height
- When you need the work done
- Any specification or named product
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Common questions from Clestrain clients
Our building in Clestrain is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
Can one quote cover a number of our buildings near Clestrain?
Yes. Planned programmes across a building, block or estate are a core part of this service. Send the addresses and photos and we will give a fixed quote.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Will residents or tenants be disturbed?
The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Planned mastic for Clestrain portfolios
With the shore within about 2 miles, Clestrain counts as a coastal location. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do. Clestrain is in the east of Scotland, which is drier than the west. Frost and condensation on winter mornings can still delay outside mastic. Block programmes are built with that in mind
For owners and agents with buildings in or around Clestrain, block-wide mastic programmes deal with frames and external joints of the same age together. Owners of student blocks near Robert Gordon University Orkney Project (to the north-west of Clestrain) can schedule frame and external mastic for the summer vacation.
Clestrain is about 9 miles west of Kirkwall, in the Orkney Islands. Businesses, contractors and managing agents in Clestrain use us for work on mastic joints. Clestrain is one of 51 places in the Orkney Islands on our list.
If you need mastic sealing in KW17, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Just outside Clestrain, we also work in Midland (2 miles south-east), Orphir (2 miles east), Clouston (3 miles north), Kirbister (3 miles east) and Stenness (3 miles north). Where a site is remote or on an island, we plan travel and materials carefully.

Why deal with it now?
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish and one 12-month guarantee. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Clestrain before they leak.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Group repairs into a planned programme
- Log resealing dates block by block
- Share your contractor requirements early
- Check sealant joints during planned building inspections
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing and the job grows.
