About our commercial sealant contractors in Chawton
How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead and the joint depth is controlled with backing rod. We work on movement joints in walls and floors, external facade joints and floor and threshold joints, and what we are called in for most is wall and floor joints that have lost their seal and frame mastic that has hardened and come away from the wall. One point of contact handles commercial sealant work in Chawton from the first photos to the final walk-round, whether it’s one building or several.
In Chawton, as anywhere, the first joints to go are typically the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.
In and around smaller places such as Chawton, 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.
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.

Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Look at the sealant around anything that has been moved or replaced
- Have extract fans checked so wet areas dry out
- Keep abrasive pads and scrapers off resealed joints
- Note dates and locations of sealant work for future planning
Put sealant on the planned maintenance checklist. Regular checks pick up small failures before they become leaks, with external elevations and wet areas first in line. Should something look amiss, you can call the office on 01277 525 020 or email the details over and send a picture.
Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.
FAQs: Chawton
Does a hotel in Chawton need to shut while its sealant is renewed?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.
Can you work at a site such as Farringdon Business Park, by Chawton?
Yes, sites like Farringdon Business Park are within our area, along with the rest of Chawton. Send details of the unit and the work through our quote form for a quick quote.
Is failed sealant stripped out, or sealed over?
Full removal is part of every quote. A bead laid on old silicone peels away.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
How is commercial sealant work priced?
Send photos, drawings or a list of locations. Where we need to see it, we will arrange a site visit, then send a fixed quote.
What site paperwork can you provide?
The paperwork is agreed with the quote: most clients ask for RAMS, our insurance certificate and CSCS details. Our applicators are CSCS-carded.
Do you check for asbestos before removing sealant?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.

Work for main contractors and building owners
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Chawton can sit alongside others in a wider programme across Hampshire.
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 will confirm with the quote.
Why act early in Chawton
Some low prices are low because nothing gets cut out. New sealant laid on old silicone has nothing to bond to, so it peels. Every quote we give includes full removal and preparation, which is where the lasting value is. One visit to deal with every failing joint makes more sense than several trips to a place like Chawton, rather than one at a time. Photos of every joint help us quote for the whole job.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

When it isn’t the sealant
Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:
- Misted, cracked or failed glazing units (a glazier’s job)
- Cracking that needs a structural engineer to look at it
- Old mastic that tests positive for asbestos
If you are not sure, just give us a call on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Different surfaces, different methods
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. The lasting answer is removal, preparation and a new sanitary bead, planned so the building keeps enough facilities in use.
Shop fronts and retail fit-outs
Shop fits put sealant right in front of customers. Counters, display units, shopfront frames and floor trims all need a neat line. Colour options are confirmed with the quote.

Firms with branches across the South East can use one contractor for every site. The area within 2 miles of Chawton holds a number of hotels. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet, and the work can be phased so the rest of the hotel keeps trading.
