Mastic sealing in Crossmichael, done properly
Before work starts, most agents and landlords want the documents in order. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on communal entrances and stairwells, communal kitchens and washrooms and external wall and movement joints, and the failures we are asked to look at most are patchy repairs in mismatched sealant and draughts at frames across a block. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Crossmichael, that means joint design, primers and backing rod as standard.
Outside mastic in Scotland needs dry joints and the right temperature, so work around Crossmichael is planned with the forecast. Programmes allow for the weather.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Looking after the joints
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Keep a record of when each building was resealed
- Prioritise elevations facing the weather
- Keep bins and bikes away from communal door frames
- Check sealant joints during planned building inspections
If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, routine checks spot the next round of repairs.
One failed perimeter typically means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
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.

Natural stone can be marked by the wrong sealant, so we pick a grade that won’t mark it.
Do you need mastic sealing in Crossmichael?
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone and the repair soon fails.
Things that normally lead to an enquiry:
- Draughts at frames across a block
- Water getting in round frames after rain
- Failed external movement joints
- Complaints coming in block by block
Property owners at sites such as Abercromby Industrial Park (2.5 miles south-east of Crossmichael) can have mastic renewed between lettings.
Questions to ask before you book
- Who will actually carry out the work
- Their pre-qualification and accreditations
- Whether primer will be used where the manufacturer specifies it
- Their approach to joint depth and backing
Why deal with it now?
Failed perimeter mastic lets cold air in around frames and the windows normally get the blame. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Early resealing prevents it.

On site: what to expect
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For work around Crossmichael, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.
- 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 sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- 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.
- Finished joints are looked over and the 12-month guarantee confirmed.
Getting the site ready
- For older buildings, check the asbestos register before work
- Move anything stored against the joints
- Send any specification or drawings in advance

Advice
Your questions answered
Can you quote for mastic across several buildings in and around Crossmichael?
Yes. Planned programmes across a building, block or estate are a core part of this service. Send the addresses and photos and we will give a fixed quote.
Will you take on work at estates like Abercromby Industrial Park, close to Crossmichael?
Yes. We cover Crossmichael and the area around it, including industrial estates, business parks and retail parks such as Abercromby Industrial Park. Send details of the unit and the work through our quote form for a quick quote.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we will tell you how we’d approach it.
Do you work in Crossmichael?
Yes. We cover Crossmichael, and you can ring 01277 525 020 or email a schedule or drawings to get started.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
