Gatehouse of Fleet is within about 2 miles of the coast. On buildings near the shore, the side facing the weather usually needs its mastic renewed first, and they deserve more regular inspection.

Signs you need mastic sealing in Gatehouse of Fleet
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
If one of these sounds familiar, it’s time for a closer look:
- Draught complaints from residents or tenants
- Patchy repairs in mismatched sealant
- Cracked, hardened mastic round windows on a block
- Failed external movement joints
Owners near Gatehouse of Fleet can renew frame and external mastic block by block on one programme.
What to look for in a quote
- Will failed sealant be removed rather than covered?
- How the joint faces will be prepared and primed
- Can the work be phased to keep areas open?
- Their public liability cover

How the quote is worked out
These are the things that shape the price:
- Phasing around occupants
- Any access equipment needed
- Location, for remote and island sites
- Quantities, in metres or numbers
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Before you send an enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- The type of building and who uses it
- Access details, including height
- The product your specification calls for
- Your programme or deadline
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or email the details over.
Questions about Gatehouse of Fleet
Is a smaller place like Gatehouse of Fleet outside your area?
Not at all. Gatehouse of Fleet is within our area. We work across every Scottish council area. Good photographs up front let us bring everything on the first visit.
Do you take on block-wide or estate-wide mastic work in Gatehouse of Fleet?
Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.
What about access for upper-floor joints?
It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How a job runs
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes one or more days per building, depending on the joint lengths and the access. For a building near Gatehouse of Fleet, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Before we start on site
- Share the asbestos register for older buildings
- Tell us what induction or permit system the site runs
- Explain the parking and delivery arrangements

After the work
Problems stay small when the joints are checked regularly. In particular:
- Ask residents or tenants to report leaks and draughts early
- Start inspections with the most exposed faces
- Track which buildings were done and when
- Make mastic part of routine maintenance checks
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Masonry that has broken away beside the joint
- Water coming in from the roof or rainwater goods
- Failed window or door frames, which need a window contractor
If you’re not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer.
