After the work
To get the most from the new sealant:
- Ask fit-out and M&E contractors to report any sealant they disturb
- Keep barriers up until the new sealant has cured
- Make sure contractors see the asbestos survey before cutting out old mastic
- Have extract fans checked so wet areas dry out
Good ventilation keeps wet-area sealant in better condition. Extraction that isn’t working keeps the joints wet, and mould follows damp. It’s worth having fans checked while the sealant is fresh.
Occupiers often notice failing sealant before the facilities team does, and in a hotel, office or shop it makes the whole space look neglected. Replacing it on a planned cycle keeps complaints down.

What happens if it’s left?
Spot repairs have their place. If the rest of the bead is the same age and product, though, it’s typically close behind, and a second visit means paying for access and set-up again. Where it helps, we quote a patch and a full reseal side by side. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

General trades versus a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Our process
Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Work in places the size of Sunninghill is planned as a single visit where we can. Clear photos and measurements help us bring the right products.
- We start with the evidence: photographs, drawings or a look on site.
- A fixed quote follows, with removal and preparation included.
- Sequence, access and working times are settled before the first joint is touched.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- Completed areas are signed off with you under our 12-month guarantee.
Getting the site ready
- Tell us which areas need to stay in use
- For older buildings, check the asbestos register before work
- Send your site hours and access windows
Getting a fixed quote
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or email the details over to discuss it first.

Commercial sealant contractors in Sunninghill: the local picture
A number of hotels sit less than 2 miles from Sunninghill. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes, and the work can be phased so the rest of the hotel keeps trading. Sunninghill sits in one of the drier corners of the country, the South East. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it.
Premises within reach of Ascot station, 1 mile west of Sunninghill, often have busy frontages where joints are seen by everyone passing. In hotels such as Highclere Hotel, which lies east of Sunninghill, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. For tenants and agents on sites such as Ascot Business Park, 1 mile to the west of Sunninghill, office fit-outs, reception joints and window perimeters are the usual sealant work.

Common questions from Sunninghill clients
Will you take on work at estates like Ascot Business Park, close to Sunninghill?
Yes. Our area takes in Sunninghill and its surroundings, with estates and business parks such as Ascot Business Park included. To start, just phone 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Is Sunninghill too small for you to travel to?
No. Places such as Sunninghill are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
How do we get a quote?
Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. To get a fixed price, send details through our quote form, or phone or email us.
What site paperwork can you provide?
The paperwork is agreed with the quote: most clients ask for RAMS, our insurance certificate and CSCS details. Every applicator holds a CSCS card.
Is it OK to apply fresh sealant over existing beads?
Every failed bead is cut out completely. New sealant can’t grip the old bead, so laying over it never lasts; the faces are then cleaned and prepared.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Owners, agents and contractors
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Surface by surface
Fire-rated seals where specified
Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. The design and sign-off of fire stopping belong to the designer and building control; we install what’s specified.
Commercial kitchens and tea points
Gaps and ragged beads trap dirt that cleaning can’t reach, and cleanability is part of what an inspector looks at. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.
