Leave it or put it right?
Some low prices are low because nothing gets cut out. Sealing over looks tidy at handover, then lifts once the joint starts moving. Every quote we give includes full removal and preparation, because that’s what makes the new bead last. Around Lower Upnor, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Commercial sealant contractors for commercial buildings in Lower Upnor
Sealant joints are easy to overlook until one lets water in, and in an occupied building failure normally announces itself as a stained ceiling or an unhappy tenant. We’re commercial sealant applicators for FMs, managing agents, landlords and contractors with sites in Lower Upnor. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. If you are dealing with mouldy silicone around WCs, urinals and vanity tops and earlier reseals applied straight onto the failed bead, we can put it right, on floor and threshold joints, washrooms and tea points and movement joints in walls and floors alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Lower Upnor, that means joint design, primers and backing rod as standard.
A lot of what we do in Lower Upnor is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
A job in a smaller place like Lower Upnor is usually a single building. We’ll want a full list and photos first, so the right products come on the day and nothing waits for a second trip.
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.

What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Phasing around occupants
- Specialist products, such as fire-rated or hygienic sealants
- Location, for remote and island sites
- The site’s rules and procedures
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.
Before you send an enquiry
A few photos plus some basic facts will normally do. Please tell us:
- When you need the work done
- Clear photographs of the problem areas
- Drawings or a marked-up plan, if available
- Whether an asbestos survey exists

Lower Upnor: questions and answers
Can being near the sea in Lower Upnor affect the sealant we need?
It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Will our hotel in Lower Upnor need to close for the work?
Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How long does a typical visit take?
It depends on the scope, though a typical visit usually takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. For bigger or phased jobs, we will set out a timescale with the quote.
Could the old sealant in an older building contain asbestos?
We check the asbestos register or survey before any old sealant is disturbed. The duty to manage asbestos sits with the dutyholder.
How is commercial sealant work priced?
Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. To get a fixed price, send details through our quote form, or phone or email us.
Do you take on multi-site sealant work?
Yes. We take on runs of jobs across portfolios as well as single sites, priced site by site or as one programme.
On site: what to expect
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For a building around Lower Upnor, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- Send details through our quote form, or ask for a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Where parts of the building must stay open, the work is phased.
- Old sealant is cut out completely, never sealed over.

- A final walk-round, then the 12-month guarantee applies.
Getting the site ready
- Point out any areas we must not close
- Have the specification and drawings to hand
- Clear stock, furniture or equipment away from the joints

Advice
What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Faulty windows rather than failed perimeter sealant
- Walls or slabs moving more than any sealant can take
- Roof leaks that only look like a joint problem
If you’re not sure, just call 01277 525 020 or email us and we’ll give you a straight answer before you book.
Joints and surfaces we work on

Signs you need commercial sealant contractors in Lower Upnor
If sealant tears through its centre, it has failed cohesively. Usually the movement was too much for the sealant chosen: a bead laid too thin, an over-stretched joint or the wrong movement class. Replacing it like for like rarely holds.
Look out for the following:
- A top-up bead over failed sealant, now lifting
- Expansion joints with the sealant torn out
- Untidy joints in a reception, shop floor or lobby
- Water staining near frames, panels or ceilings
Offices and shops close to stations such as Strood station, 1.6 miles south-west of Lower Upnor, tend to be busy all day, so sealant work is planned around opening hours.
Before you book anyone
- Health and safety accreditation such as CHAS
- Who will actually carry out the work
- Whether old or failed sealant will be cut out, not overlaid
- Proof of insurance
Commercial sealant contractors around Lower Upnor: how the place shapes the job
Lower Upnor sits close to the coast, within about 2 miles. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. Where a frontage needs a particular colour, the product still has to suit that exposure. Central London is about 27 miles from Lower Upnor.

Firms with branches across the South East can use one contractor for every site.
