About our coloured sealant in Lower Upnor

Stone, brick and cladding each bring their own colour challenge: a stone or brick facade shifts in tone from one area to the next. We choose a colour that reads well across the surface rather than chasing one spot. If you have weathered sealant that no longer matches and colour changes after a rebrand or refit, we can put it right, on cladding panels, natural stone and brick and shop-fit joinery and counters alike. Searching for sealant specialists in Lower Upnor? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

In and around smaller places such as Lower Upnor, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Each has kitchens, washrooms and frames whose joints need renewing in time.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How the job changes by surface

Natural stone

Sandstone, limestone and granite each have distinct tones. Colour is agreed on site where possible before the full run.

Powder-coated and anodised frames

Window, door and shopfront frames in RAL colours often need a sealant to suit. The frame colour is checked against what the product is made in.

What Lower Upnor’s businesses ask us to seal

With the shore within about 2 miles, Lower Upnor counts as a coastal location. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. We choose a product rated for the exposure, then confirm the colours available for it. A good number of hotels sit less than 2 miles from Lower Upnor. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme, with rooms done in turn while the rest stay let.

In hotels such as King Charles Hotel (1.5 miles south of Lower Upnor), refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. Shopping centres and retail parks such as Strood Retail Park (1.9 miles south-west of Lower Upnor) see a steady turnover of shop fits, each leaving joints where colour and finish matter. On estates like Pier Road Industrial Estate, 1.6 miles to the south-east of Lower Upnor, the office and welfare end of each unit has its own sealant to maintain.

Lower Upnor is about 2 miles north-east of Rochester, in Medway. We cover commercial sites throughout Lower Upnor, for single jobs and planned programmes alike.

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Exact bespoke colour matches beyond the product’s range
  • Preventing all fading from sunlight and weathering
  • Colour variation across natural stone or brick that no single shade can match

Not sure which it is? You can phone 01277 525 020 or use the quote form and we will tell you honestly before you book.

Joints and surfaces we work on

FAQs: Lower Upnor

Our building in Lower Upnor is near the coast: does that change the sealant?

It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Is Lower Upnor too far out for you?

Not at all. Lower Upnor is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Do you match sealant to RAL colours?

Yes. RAL references are a common way to specify sealant colour. We will confirm the colours available for the specified product.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, which many sites require.

After the work

After handover, a little attention goes a long way:

  • Settle the colour with the designer at the start
  • Keep the same sealant colour across a brand
  • Brief cleaners about newly sealed joints
  • Don’t let trades patch coloured joints with a random sealant

Expect some change in appearance over the years. Some fading is part of normal ageing outdoors.

Settle the colour early in the project. When colour is left to the last minute, it is often wrong; fixing it early prevents rework.

Work for main contractors and building owners

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Our process

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near Lower Upnor need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. First we agree which sealant type the joint needs.
  2. Your RAL reference, sample or photo is checked against that product’s colours.
  3. You approve the colour, on site if it’s critical.
  4. We cut out the existing bead, clean and set the depth.
  5. We mask, seal and tool to a clean line.
  6. Masking comes off and the work is checked with you.

Preparing the site

  • Move anything stored against the joints
  • Explain the parking and delivery arrangements
  • Confirm the product named in the specification
