Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Looking after the joints
After handover, a little attention goes a long way:
- Note which sealant went where at handover
- Brief following trades on areas that have been sealed
- Ask cleaners to use soft cloths around fresh sealant
- Check frame gaps are within the sealant’s range before sealing
After we have sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Holding off until conditions suit avoids callbacks.
Construction mastic in Dunning, done properly
Getting a subcontractor through site induction should be simple. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. We work on cladding and panel joints, brick and block movement joints and window and door perimeters, and the usual reasons a site gets in touch are a mastic package split between trades with no clear owner and old sealant on a refurbishment that needs stripping before new work. For commercial sealant work in Dunning, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
For a site around Dunning, we plan the mastic in as few trips as the programme allows. Send drawings, photos and the programme so everything needed arrives on the first day.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Site staff or a sealant specialist?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
For managing agents and facilities managers
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Contractors’ notes for Dunning
The east of Scotland, where Dunning is, gets less rain than the west. Frost and condensation on frames and panels can still hold up external mastic on winter mornings. We programme around it with the site team. In Dunning, as across Scotland, building warrants are issued by the local authority verifier under the Scottish regulations. The mastic follows the specification that goes with the warrant.
Extensions at sites like St Margaret's Hospital, 5.3 miles west of Dunning, normally sit beside working departments, and the mastic follows strict access rules.
Dunning is about 8 miles south-west of Perth, in Perth and Kinross. Across the PH2 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

Questions we are asked in Dunning
Is a smaller place like Dunning outside your area?
Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.
Do you take on work at healthcare sites like St Margaret's 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.
How long does a typical visit take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Will you stick to the specified products?
We use the product the specification names. If we think an alternative would suit better, we put it to you first.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
What joints do you seal on a new build?
It depends on the specification, but most packages include frame perimeters, sanitary and kitchen joints, caulking where specified and a snagging pass.
Why act early in Dunning
Some packages split mastic across the window fitter, kitchen fitter and plumber. The result tends to be uneven finishes and arguments about who should seal what. A single mastic package gives one point of responsibility, with the same standard on every plot. Around smaller places like Dunning, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Early resealing prevents it.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

When to call us in Dunning
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, and the joint has to be redone.
It’s worth sending us details if you spot any of the following:
- Frame perimeters left unsealed or poorly sealed
- A mastic package split between trades with no clear owner
- Existing joints on a refurb that need cutting out and resealing
- Mastic snags holding up handover
Sites around Dunning get mastic sealed to the drawings and the programme, nothing improvised.
What your quote should include
- Whether primer will be used where the manufacturer specifies it
- Their plan for phasing and protecting the area
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How long is the guarantee, and what does it include?
