Construction mastic across Rochester Riverside
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Joint design decisions that belong to the architect or engineer
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Approving fire stopping as compliant
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.
Surfaces we seal
- Cladding and panel joints
- Window and door perimeters
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Floor and skirting junctions
- Brick and block movement joints
Construction mastic in Rochester Riverside, done properly
Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up. Internal areas can usually carry on while the outside waits. We work on sanitary and kitchen joints, brick and block movement joints and floor and skirting junctions, and what we are called in for most is oversized or tapered gaps around new frames and cracks opening in caulked internal joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Rochester Riverside, preparation and product choice get the time they need.
Conversions around smaller places like Rochester Riverside often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement, in a colour the planners or architect are happy with.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Leave it or put it right?
Getting the mastic contractor involved early pays off. Early involvement means gaps, products and access are sorted before the programme bites, which avoids last-minute problems. Called in at the end, the same issues surface during handover. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
Access often affects the price as much as the sealing: 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.

Advice
Aftercare for building managers
Regular inspection catches problems early. In particular:
- Ask cleaners to use soft cloths around fresh sealant
- Keep finished joints away from paint, plaster and scrapers
- Use the product the specification names
- Check frame gaps are within the sealant’s range before sealing
Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
How the job changes by surface
Fire-rated sealant where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services so we’ll flag where the detail needs something different. Tell us what records you need and we’ll confirm with the quote.
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification.
FAQs: Rochester Riverside
Will you plan work around the academic year at somewhere like University for the Creative Arts - Rochester?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can being near the sea in Rochester Riverside affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
What will the job cost?
There isn’t a price list, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Can fire-rated sealing at service penetrations be included?
Where it’s specified, yes to the tested detail. We will flag if the detail needs a different product.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Can you quote from photographs?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.
Facades, frames and programmes in Rochester Riverside
With the shore within about 3 miles, Rochester Riverside counts as a coastal location. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. The area within 2 miles of Rochester Riverside holds plenty of hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
Further education sites such as MidKent College Gillingham Campus, 1.5 miles east of Rochester Riverside, are extended and refurbished from time to time, with mastic often programmed into the summer break. For a contractor at a hotel such as The Gordon Hotel, which lies south-west of Rochester Riverside, the mastic often has to be finished before a reopening date. New wings at hospitals like Medway Maritime Hospital, 1.6 miles to the south-east of Rochester Riverside, bring long runs of window and panel joints to seal.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
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. That’s why many clients bring in a specialist from the beginning.
