About our mastic sealing in Devonside
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint. We’ll confirm the colours available for the specified product. We work on external wall and movement joints, window and door perimeters on blocks and shopfronts below residential blocks, and what we’re called in for most is damaged joints in communal entrances and corridors and no planned programme for sealant. A specialist sealant contractor works differently from a general builder: on jobs in Devonside, preparation and product choice get the time they need.
For buildings around Devonside, we group the work to keep travel and visits down. A list of addresses and photographs lets us quote for them together.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Diagnose, treat, sign off
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking one or more days per building, depending on the joint lengths and the access. Travel to smaller Scottish places like Devonside is planned so the job is finished in one visit where possible, which is why we ask for photographs and a full list first. External joints need a dry spell as well.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready
- Arrange parking or a loading space
- Move anything stored against the joints
- Send any specification or drawings in advance

Questions we are asked in Devonside
Do you work in occupied care homes around Devonside?
Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.
Can you work at a site such as Industrial Estate, by Devonside?
Yes. We cover Devonside and the area around it, including industrial estates, business parks and retail parks such as Industrial Estate. A few photos and the unit address let us price the work.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Can you take on resealing for a block portfolio?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
How many days will you need on site?
That varies with the scale of the job, but the work typically takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Aftercare for building managers
Regular inspection catches problems early. In particular:
- Check sealant joints during planned building inspections
- Encourage occupiers to report problems at frames
- Keep a record of when each building was resealed
- Protect low-level joints in entrances
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.

Being in the east of Scotland, Devonside gets less rain than the west coast. External mastic still needs a dry joint and the right temperature, and winter mornings can be frosty. Three care or nursing homes sit less than 2 miles from Devonside. Owners of care premises can bring window and door mastic into a phased programme planned around the home.
Schools and community buildings such as Alva Academy need frame and external mastic kept sound like any building. Buildings close to stations like Alloa station (2.7 miles south-west of Devonside) are often flats over shops, with frame mastic to keep sound.

Do you need mastic sealing in Devonside?
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. We’ll tell you if the joint edges need repairing before resealing.
If one of these sounds familiar, it’s time for a closer look:
- A mix of products and colours from past repairs
- Occupiers reporting cold air round windows
- Complaints coming in block by block
- Mastic failing across several blocks on an estate
If you own or manage units on a site such as Industrial Estate (1.8 miles west of Devonside), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

How the job changes by surface
Estate-wide resealing programmes
A programme can start with the worst buildings and work down. Quotes can be per block or for the full programme.
Tenement and older buildings
Older mastic can contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
