About commercial sealant contractors in PO6
Pricing a commercial reseal is a short process. Our quote form takes photos, drawings or a schedule of the areas. Where the photos don’t tell the full story, we arrange a site visit, and a fixed quote for the agreed scope follows. Most enquiries involve mouldy silicone around WCs, urinals and vanity tops and shrunken sealant along kitchen worktops and splashbacks, across floor and threshold joints, washrooms and tea points and kitchen worktops and splashbacks.
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out.
- 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.
- Every failed bead is removed rather than covered.
- A suitable product for each joint goes in at the right depth and is tooled.
- A final walk-round, then the 12-month guarantee applies.

Shops, offices and hotels in PO6
Across PO6, from Purbrook, Portchester and Hilsea to the smaller places between, commercial buildings run from high-street shops and offices to hotels, schools and business parks. Because we cover all of it, multi-site occupiers can bring every building under one quote, with colours matched site to site where the brand needs it.
London and the South East are among the drier parts of the UK, but external sealing in PO6 still needs a dry joint and the right temperature, and damp or frosty mornings can hold it up. Parts of PO6 lie on or near the coast, where wind-driven rain and, closer to the shore, salt air are harder on external joints. We take that exposure into account when choosing the product.
Portsmouth: In hotels such as The Avenue Hotel, 1 mile north of Portsmouth, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. Units at retail parks like Victory Retail Park, 0.5 miles to the west of Portsmouth, change hands and get refitted, with new joints at every frontage.
Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Note dates and locations of sealant work for future planning
- Brief cleaning contractors to avoid scourers and blades on sealant
- Look at the sealant around anything that has been moved or replaced
- Respect the cure time before reopening an area
Put sealant on the planned maintenance checklist. A periodic look catches splits and lifting edges early, with external elevations and wet areas first in line. If anything looks wrong, ring 01277 525 020 or email the details over with a photo.
A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.
Site staff or a sealant specialist?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
How the quote is worked out
Before we quote, we look at:
- Access and working height
- The site’s rules and procedures
- Whether old sealant has to be cut out first
- Backing rod, priming and other preparation
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Before you send an enquiry
However big the job, the same details help:
- Access details, including height
- What the building is and how it’s used
- Where the site is, with the postcode
- Drawings or a marked-up plan, if available
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or email the details over to discuss it first.
What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Structural cracks or movement the joints weren’t designed for
- Faulty windows rather than failed perimeter sealant
Signs you need commercial sealant contractors
Outside, sunlight and rain wear sealant down year after year. UV hardens the surface while wind and rain work at the edges; in time the surface chalks, hardens and cracks. A hardened bead can’t follow the building any more.
What tends to prompt an enquiry:
- Hardened, chalky sealant on south-facing or exposed elevations
- Greasy, split joints in a kitchen or tea point
- Frame sealant that has cracked, shrunk or pulled away
- Untidy joints in a reception, shop floor or lobby
Questions about PO6
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Do you check for asbestos before removing sealant?
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.
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 inspection is the best way to catch problems early.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
Is failed sealant stripped out, or sealed over?
The old bead is stripped out first. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.
