How we handle mastic sealing in Gelston
Managing agents and housing associations usually need paperwork before anyone starts. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are a Constructionline member and CHAS accredited, and we carry public liability insurance. If you have water getting in round frames after rain and draught complaints from residents or tenants, we can put it right. Most enquiries from Gelston start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In smaller Scottish places like Gelston, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Exposed walls take Scottish weather hard, and frame mastic shows it first.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

When to call us in Gelston
Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified it comes away from one face.
These are often picked up first by site or facilities staff:
- Brittle perimeter mastic across a building
- Damp patches beside frames
- Worn sealant at communal door frames
- Mastic failing across several blocks on an estate
For owners and agents with buildings in or around Gelston, block-wide mastic programmes deal with frames and external joints of the same age together.

Gelston: questions and answers
Is Gelston off your patch?
No. Places such as Gelston are covered as much as the big towns. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.
Will you price a mastic programme across our Gelston portfolio?
Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Can you send RAMS and CSCS details before starting?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Quoting for work in Gelston
Quotes vary with the job. It mainly depends on:
- Specialist products, such as fire-rated or hygienic sealants
- Whether old sealant has to be cut out first
- The total length or number of joints
- Location, for remote and island sites
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Sending details for a quote
A few photographs plus some basic facts will normally do. It helps to include:
- The type of building and who uses it
- A wide shot and a close-up of the area
- The postcode of the building
- Access details, including height
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or email us.
Planned mastic for Gelston portfolios
Gelston 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
Churches, halls and community buildings such as Kirkland Of Gelston are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

What the job involves on each surface
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Tidy, sound joints keep them looking cared for.
Estate-wide resealing programmes
A programme can start with the worst buildings and work down. You get one fixed quote per building or for the whole estate.
For managing agents and facilities managers
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Keeping the joints sound
After handover, a little attention goes a long way:
- Encourage occupiers to report problems at frames
- Protect low-level joints in entrances
- Start inspections with the most exposed faces
- Avoid piecemeal callouts where you can
Log the date and extent of the resealing for each block. It helps plan the next round and gives you a history.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings and work down the list.
