Commercial sealant contractors in Lower Caversham, done properly
A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely, then both faces are cleaned back to sound, dry material with no dust or grease on them. Primer is used wherever the manufacturer calls for it on that surface. If you have a top-up bead over failed sealant, now lifting and weathered facade sealant that no longer flexes, we can help, on movement joints in walls and floors, kitchen worktops and splashbacks and floor and threshold joints alike. Most enquiries from Lower Caversham start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
If you look after more than one building near Lower Caversham, the work can be planned as one programme, with one quote format and one point of contact.
In a smaller place such as Lower Caversham, commercial buildings are normally a mix of shops, a pub or café, a school, a surgery and perhaps a few business units. They’re not big jobs one by one, but their joints need the same preparation as anywhere.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Aftercare for building managers
Regular inspection catches problems early. In particular:
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Look at the sealant around anything that has been moved or replaced
- Make sure contractors see the asbestos survey before cutting out old mastic
- Put external and wet-area joints on a regular inspection round
Later works are the usual way new joints get damaged. Shop refits, new services and replaced fittings often break the seal around them. Where work has disturbed a joint, just call 01277 525 020 or email us for a quote.
Occupiers often notice failing sealant before the facilities team does, and it reflects on how the building is run. Replacing it on a planned cycle keeps complaints down.
What we can’t put right
Being straight saves everyone time. New sealant won’t cure:
- Leaks from pipework, wastes or valves (that’s plumbing)
- Old mastic that tests positive for asbestos
- Structural cracks or movement the joints weren’t designed for
Not sure which it is? You can call the office on 01277 525 020 or email us and we’ll tell you honestly before you book.
Surfaces we seal
- Movement joints in walls and floors

How a job runs
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before we move to the next. What matters most for a job in Lower Caversham is a clear list of what needs doing, so send photographs of each area. You’ll then get a fixed price for the work.
- We begin with whatever information you have, whether that’s photos, a drawing or a list of locations, or we arrange a site visit.
- Next comes a diagnosis and a fixed quote.
- Site hours, access windows and the order of areas are agreed before we start.
- We strip the failed bead and prepare both faces of the joint.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- Each area is inspected, signed off and backed by our 12-month guarantee.
Before we start on site
- Move anything stored against the joints
- Point out any areas we must not close
- For older buildings, check the asbestos register before work

Washrooms and toilets
Mould that has grown into washroom sealant can’t normally be cleaned out. Replacement is the fix: strip, clean, dry and reseal, room by room if that suits the building.
Commercial kitchens and tea points
In kitchens, sealant lines at worktops, sinks and wall panels take heat, grease and daily cleaning. They’re degreased thoroughly before resealing, and a hygienic or food-safe sealant is used where food contact is possible.

Why act early in Lower Caversham
Some managers wait for a fit-out before touching the mastic. For internal joints that are only cosmetic, that can make sense, but external and wet-area joints that already leak shouldn’t wait. We can seal the urgent joints now and leave the rest for the programme. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Pricing sealant joints depends on how many there are, their condition and the access. Call for a quote.

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.
Putting right a botched joint often costs more than sealing it well at the start, 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.
Questions about Lower Caversham
Does your area include sites such as Forbury Retail Park, near Lower Caversham?
Yes. We cover Lower Caversham and the area around it, including industrial estates, business parks and retail parks such as Forbury Retail Park. Send details of the unit and the work through our quote form for a quick quote.
Is Lower Caversham too small for you to travel to?
Not at all. Lower Caversham is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How long does a typical visit take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
What do you need from us to quote?
Start with whatever information is to hand. Questions or a site visit follow where needed.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

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.
A business with units at Forbury Retail Park and The Station Shopping Park needn’t use two contractors for its sealant.

If you look after units at a retail site such as Forbury Retail Park, 0.5 miles to the south of Lower Caversham, shopfront perimeters and shop-fit joints are where a matched colour shows.
