About our facade sealing in Charlestown
Managing agents and owners in Charlestown ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. The enquiries we see most involve weathered facade joints that have lost their grip and failed seals around shopfront and entrance frames, across stone and brick facade joints, perimeter joints where frames meet the structure and cladding panel joints. Searching for sealant specialists in Charlestown? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Charlestown that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. Travel to smaller Scottish places like Charlestown is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. External joints need a dry spell as well.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.

Facade sealing in Charlestown: the local picture
With the shore within about 2 miles, Charlestown counts as a coastal location. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Being in the east of Scotland, Charlestown gets less rain than the west coast. Frost and condensation on frames and panels can still hold up external mastic on winter mornings. External dates keep a little give.
Work at a hotel such as Aberdeen Altens Hotel (to the north-east of Charlestown) tends to be programmed around bookings, mastic included. Hospital estates such as Albyn Hospital (to the north of Charlestown) 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. School extensions, at buildings such as Lochside Academy, usually run to the summer holidays, mastic included.

After the work
Regular inspection catches problems early. In particular:
- Brief window cleaners about newly sealed joints
- Keep sills, gutters and drainage paths clear
- Ask about asbestos in pre-2000 mastic
- Investigate damp beside windows promptly
Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.
Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in.
Charlestown: questions and answers
Does the sea air around Charlestown change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Can you work around term dates at a campus such as Robert Gordon University?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Which sealant do you use on facades?
It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Is it okay to overlay old mastic?
No. New sealant won’t hold on old sealant, so the old bead is cut away and the faces are cleaned before resealing. Nothing else gives a bond that lasts.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.

How the job changes by surface
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod with primer where the product requires it.
Coping and flashing joints
Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.
Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Installing or repairing glazing systems
- Water getting in through cracked render or porous masonry
- Arranging specialist high-level access, which is planned with the client
If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Commercial clients in Charlestown

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Site staff or a sealant specialist?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
