Our process
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. Where we can, we combine work around Canonbie with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.
- Send details through our quote form, or ask for a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
Before we start on site
- Tell staff and tenants when we will be in
- Share the asbestos register for older buildings
- Explain the parking and delivery arrangements

Advice
About our commercial sealant contractors in Canonbie
How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead, and a backing rod limits the depth to give the sealant room to work. The enquiries we see most involve black mould through washroom sealant that won’t clean off and layers of sealant, all of them failing, on window and door perimeters, floor and threshold joints and external facade joints. Whoever orders the work in Canonbie, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
On a typical commercial building in Canonbie, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.
For work in and around Canonbie, we’d rather do everything on one trip: send photos and a complete list so the right products and colours come on the day. Several jobs nearby can also be put together.

Canonbie: questions and answers
What paperwork can you provide for a job in Canonbie?
RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Can you match sealant colours for premises in Canonbie?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. The quote lists the colours the product is made in.
Could the old sealant in an older building contain asbestos?
It can, on some older buildings. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Is Canonbie in your area?
Yes. Sites across Canonbie are covered.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
Aftercare for building managers
For the best life from the joints:
- Brief cleaning contractors to avoid scourers and blades on sealant
- Add sealant to the planned maintenance inspection list
- Deal with small splits before they become leaks
- Check joints after other trades have worked nearby
Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life; a mild cleaner is all most joints need.
Occupiers often notice failing sealant before the facilities team does. Replacing it on a planned cycle keeps complaints down.
Why deal with it now?
Leaving a failed joint rarely saves money. Once water gets behind the seal, finishes and ceilings underneath are next, and the bill then involves other trades. Dealing with it while the damage stops at the bead is the cheaper route. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Early resealing prevents it.
Pricing sealant joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.
Why appoint us
- Specification-led, product-correct work
- Sealing commercial buildings since 2005

How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Working within restricted access windows
- Quantities, in metres or numbers
- Specialist products, such as fire-rated or hygienic sealants
- Whether old sealant has to be cut out first
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
Details that help us quote
Good information means a firmer quote. Helpful details to send:
- Specification clauses that apply
- Photos of the joints, close up and from further back
- What the building is and how it’s used
- Asbestos survey details if the building is older
For a fixed quote, phone 01277 525 020 or email the details over, telling us the site location and the nature of the job. Our quote form is another easy route.
What we’re called out for in Canonbie
Resealing over the top is a false economy we come across often. Fresh sealant won’t stick to the old bead underneath, so the top layer lifts, holds water and hides what’s going on. Getting back to a clean joint then means removing every layer.
Look out for the following:
- Expansion joints with the sealant torn out
- Water staining near frames, panels or ceilings
- Earlier reseals applied straight onto the failed bead
- Shrunken sealant along kitchen worktops and splashbacks
In hotels such as Cross Keys Hotel (under half a mile south of Canonbie), refurbishments normally mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.
What your quote should include
- Their public liability cover
- Which product they’ll use, and why it suits the joint
- Whether their applicators hold CSCS cards
- Will failed sealant be removed rather than covered?

Doing it in-house
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
