Common questions from Belses clients
Can you work on a hospital site such as Dingleton Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Can you keep pace with our programme in Belses?
Yes, we work to the programme and the sequence the site sets. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
What joints do you seal on a new build?
External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. We price to the specification and drawings.
Can you work to our specification?
We follow the specified sealant. Product standards such as BS EN 15651 are often named in specifications.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you quote from photos?
It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs usually get a visit.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Construction mastic in Belses
Getting a subcontractor through site induction should be simple. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. If you have inconsistent sealant finishes from plot to plot and sealant knocked or painted over by other trades, we can help, whatever the surface. For commercial sealant work in Belses, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Sites near smaller places like Belses can mean longer travel, so the mastic is planned with as few trips as the job allows. Send drawings, photographs and the programme so everything needed arrives on the first day.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why deal with it now?
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go and saves applicators coming back again and again. Snagging can be priced as a separate stage. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Resealing early avoids that.
A quote for mastic packages depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

When to bring in a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Where we can, we combine work around Belses with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.
- First we take quantities off the drawings and read through the specification.
- You receive a fixed quote listing scope, products and phasing.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Every joint is prepared, set to depth and sealed with the specified product.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Preparing the site
- Arrange parking or a loading space
- Let us know about inductions and permits
- Tell staff and tenants when we’ll be in
Getting a fixed quote

Scotland has its own building regulations, and in Belses warrants come from the local authority verifier. The mastic follows the specification that goes with the warrant.
On any site in or around Belses, the mastic follows the specification and the programme.

Common problems we fix in Belses
On construction sites, joints typically fail early because of when they were sealed, not what was used. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage.
Common reasons buildings call us in:
- Failed sealant in an existing building being refurbished
- Window and door perimeters that won’t pass inspection
- Cracks opening in caulked internal joints
- Oversized or tapered gaps around new frames
Hospital estates such as Dingleton Hospital (5.4 miles north of Belses) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
What to look for in a quote
- How joint depth will be controlled
- Are they CHAS accredited or on Constructionline?
- How they handle RAMS and site documents
- Whether their applicators hold CSCS cards
Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients 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.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
What we can’t put right
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Approving fire stopping as compliant
- Joint design decisions that belong to the architect or engineer
- Joints damaged after sign-off by following trades
If you are not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
Surfaces we seal
- Cladding and panel joints
- Internal decorators’ caulk
- Floor and skirting junctions
- Sanitary and kitchen joints
- Brick and block movement joints
- Window and door perimeters
