Your questions answered
Is Forth off your patch?
No. Small places get the same service as large ones. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.
Will you fit the mastic around our build programme in Forth?
Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you guarantee new-build sealant work?
Our workmanship carries a 12-month guarantee from sign-off. Damage by others after we’ve finished isn’t covered.
Can you quote from photos?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.
How do you work with the site programme?
Working to your programme, we seal each area as it’s handed over. The sequence is agreed with the site manager at the start.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Can fire-rated sealing at service penetrations be included?
We install fire-rated sealant where it is the specified product to the tested detail. If the detail calls for collars, wraps or batts instead, we’ll tell you.
Construction mastic in Forth
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. If you’re dealing with different trades sealing to different standards and frame perimeters left unsealed or poorly sealed, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Forth, preparation and product choice get the time they need.
External sealing around Forth depends on dry faces and the right temperature. A little flexibility in the programme lets external joints go in on suitable days.
Our workmanship is guaranteed for 12 months, in Forth as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What else we do in Forth
Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Release areas for mastic once other trades have finished in them
- Ask installers to correct oversized gaps first
- Use the product the specification names
- Ask cleaners to use soft cloths around fresh sealant
Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean so keep them off the joints.
Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors. Getting the product and preparation right first time avoids that.
Different surfaces, different methods
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. Snagging can be included or priced separately.
External facade and movement joints
External movement joints often need primer, depending on the substrate. Primer goes on where the sealant maker calls for it.
Cost factors for mastic packages
These are the things that shape the price:
- Joint width, depth and condition
- Quantities, in metres or numbers
- Whether the work must be split into stages
- Site requirements such as inductions and permits
Pricing mastic packages depends on how many there are, their condition and the access. Ask us for a fixed quote.
What we need to price the job
Whether it’s one area or a whole building, these details speed things up:
- Approximate linear metres or a joint schedule
- Where the site is, with the postcode
- A wide shot and a close-up of the area
- Whether the building will be occupied during the work
Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, speak to us on 01277 525 020 or send details through our quote form.
Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
Diagnose, treat, sign off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. For a building near Forth, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- We seal each plot or floor as it’s released to us.
- Every joint is prepared, set to depth and sealed with the specified product.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Before we start on site
- Send your site hours and access windows
- Point out any areas we must not close
- Arrange parking or a loading space
Getting a fixed quote
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Common problems we fix in Forth
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We stick to the specified product, or put any alternative to you first.
Things that typically lead to an enquiry:
- Mastic snags holding up handover
- Early adhesion failures on new external joints
- Window and door perimeters that won’t pass inspection
- Caulk cracking where joints are moving more than expected
A facade joint near Forth lasts when width, depth and backing are right, not just the finish.
What to look for in a quote
- What site paperwork they can supply
- How the joint faces will be prepared and primed
- Is the sealant right for the movement and the substrate?
- Whether their applicators hold CSCS cards
Building and refurbishing in Forth
Building work in Forth comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. Our job is to seal to that specification. The east of Scotland, where Forth 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.
