Questions about Charlestown
Can you work on a hospital site such as Albyn Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is Balmoral Business Park, near Charlestown, within your area?
Yes. Our area takes in Charlestown and its surroundings, with estates and business parks such as Balmoral Business Park included. A few photos and the unit address let us price the work.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Are you CHAS accredited?
We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. Public liability insurance of five million pounds is in place too.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
How we handle construction mastic in Charlestown
Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list and clearing them late eats into the handover window. Our aim is joints that pass at the first inspection, area by area through the programme. Most enquiries involve sealant knocked or painted over by other trades and missed perimeter joints on a new elevation, across internal decorators’ caulk, floor and skirting junctions and window and door perimeters. Facilities teams, main contractors and managing agents in Charlestown tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
External sealing around Charlestown depends on dry faces and the right temperature. A little flexibility in the programme lets external joints go in on suitable days.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Sites and facades in and around Charlestown
The sea is no more than about 2 miles from Charlestown. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. The area within 2 miles of Charlestown holds several hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
School extensions, at buildings such as Lochside Academy, typically run to the summer holidays, mastic included. For contractors refurbishing units at places like Balmoral Business Park, which lies north-east of Charlestown, the mastic covers cladding panels, roller-door and window perimeters.

Our process
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. For work around Charlestown, we aim for one trip, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised right away.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Explain the parking and delivery arrangements
- Send your site hours and access windows
Getting a fixed quote
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Why it’s worth doing now in Charlestown
When a package runs over budget, downgrading the product is a common first thought. The saving is small next to the cost of callbacks and defects. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Renewing every failing joint on one visit is the sensible approach for a place like Charlestown. Photos of each area help us quote the whole job.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Why appoint us
- CHAS accredited contractor
- Colours confirmed for the specified product
- Fully insured
- Constructionline member

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Flag uneven or tapered frame gaps early
- Brief following trades on areas that have been sealed
- Keep product details for future maintenance
- Share drawings and the specification as soon as possible
Any damage after we’ve finished should go on the snag list straight away. We can return to clear snags before handover.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels, and the repair falls into the defects period. Proper preparation, with the right silicone first time, keeps it off the defects list.
What else we do in Charlestown
Common problems we fix in Charlestown
A new building moves while it dries and settles. Materials lose construction moisture and shrink and internal caulk in a moving joint is typically the first to crack. Picking a flexible sealant where there’s movement keeps snags down.
Look out for the following:
- Early adhesion failures on new external joints
- Perimeter gaps outside the sealant’s range
- Sanitary sealant damaged by following trades
- Old sealant on a refurbishment that needs stripping before new work
New wings at hospitals like Albyn Hospital (2.9 miles north of Charlestown) bring long runs of window and panel joints to seal.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- Their plan for phasing and protecting the area
- How the existing material will be dealt with
- Will RAMS and insurance details be available?
How the quote is worked out
Each job is priced on its own details. The things that drive the figure:
- Distance, for remote addresses
- Any access equipment needed
- Which sealant the job calls for
- The site’s rules and procedures
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What we need to price the job
A few photos plus some basic facts will normally do. It helps to include:
- Asbestos survey details if the building is older
- How the joints are reached, and at what height
- Any specification or named product
- Rough lengths or quantities, or drawings if you have them
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
