Signs you need facade sealing in Lower Upnor
When the sealant tears down its centre, it has normally been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
Site and facilities staff are often the first to spot these:
- Air leaks through failed facade joints
- Cladding panel joints that have opened up
- Weathered facade joints that have lost their grip
- Previous reseals run over old sealant
Hotels like King Charles Hotel, 1.5 miles to the south of Lower Upnor, rarely close for long, so refurbishment mastic is phased floor by floor.
Before you book anyone
- Their pre-qualification and accreditations
- Will failed sealant be removed rather than covered?
- Can the work be phased to keep areas open?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Facade sealing in Lower Upnor, done properly
Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range. We plan for that and keep you updated. The enquiries we see most involve gaps between rainscreen or cladding panels and perimeter joints where frames meet the structure, across shopfront frames, perimeter joints where frames meet the structure and coping and flashing joints. Whoever orders the work in Lower Upnor, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Construction in and around smaller places such as Lower Upnor is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Keep pressure washers away from fresh sealant
- Don’t wait for a second leak before calling
- Plan facade sealing alongside redecoration
- Ask about asbestos in pre-2000 mastic
Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal without guesswork.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and cuts time on site.
General trades versus a specialist
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.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Jobs in and around smaller places like Lower Upnor are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- We start with photographs, drawings or a visit to see the joints and agree access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
Getting the site ready
- Make sure the joints can be reached
- Agree which areas must stay open
- Confirm the product named in the specification

Advice
Common questions from Lower Upnor clients
Can being near the sea in Lower Upnor affect the sealant we need?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Will you plan work around the academic year at somewhere like University of Greenwich - Medway?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Can you work while the building is occupied?
Typically, yes. We phase the work so most of the building stays in use, with each area protected and signed.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
What site paperwork can you supply?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, which many sites require.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure.

Facade sealing around Lower Upnor: what changes locally
Lower Upnor is within about 2 miles of the coast. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. The area within 2 miles of Lower Upnor holds plenty of hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
When units on a site such as Pier Road Industrial Estate, 1.6 miles south-east of Lower Upnor, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Further education sites such as MidKent College Gillingham Campus, 1.4 miles to the south-east of Lower Upnor, are extended and refurbished from time to time, with mastic often programmed into the summer break.
Lower Upnor is about 2 miles north-east of Rochester, in Medway. Anywhere in ME2, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 54 places in Medway, from busy centres to rural villages. For work in that direction, see our London page.

How the job changes by surface
Precast concrete panels
Joints between precast panels carry real movement. We use a sealant with the right movement capability, set over backing rod, primed where the maker specifies.
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather, so preparation and product choice matter.
Honest limits
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Arranging specialist high-level access, which is planned with the client
- Joints too narrow for the movement they take, which need redesign
- Replacing glass or failed glazing units
If in doubt, call 01277 525 020 or send photos by email and we will say what we think before you book.
