When to call us in Eton
Mould and staining discolour coloured joints in some areas. Mould that has grown into sealant typically can’t be cleaned out.
Any of the following is a good reason to get the joints checked over:
- White or grey sealant that clashes with the finish
- Patch repairs in several different colours
- Marked sealant in hotel bathrooms
- Smeared sealant on stone or joinery
Shops and cafés around stations like Windsor & Eton Riverside station, 0.5 miles south of Eton, trade from early, so work is timed around them.
What to look for in a quote
- Health and safety accreditation such as CHAS
- Their approach to joint depth and backing
- Whether primer will be used where the manufacturer specifies it
- Proof of insurance
Coloured sealant for commercial buildings in Eton
Window, door and shopfront frames in RAL finishes often need a sealant to suit. The frame colour is checked against the sealant’s standard range. Where nothing in the range is close enough, a paintable hybrid or PU sealant may be an alternative, if the joint and specification allow. Site teams most often ask us about shop fits that need consistent sealant colours across sites and previous reseals that don’t match the original, on office fit-out finishes, natural stone and brick and shop-fit joinery and counters. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Eton is the same: the right product in a properly prepared joint.
Rural business units near smaller places such as Eton are frequently converted agricultural buildings. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Common questions from Eton clients
Do hotels near Eton have to close for sealant work?
Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we’ll plan around them.
Is Eton too far out for you?
Not at all. Eton is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
How long does a job like this take?
That varies with the scale of the job, though a typical visit normally takes a few hours or a phased programme, depending on joint lengths and how many colours are involved. For bigger or phased jobs, we will set out a timescale with the quote.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Do you have public liability insurance?
Yes. We are fully insured, and the certificate can go with your quote.
Can staff carry on working while you’re here?
Normally, yes. We phase the work so most of the building stays in use.
Commercial premises in Eton
Eton sits in one of the drier corners of the country, the South East. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings. The 3 miles around Eton take in at least three named trading estates, business parks or retail parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal, often in a colour the occupier specifies.
Retail sites such as Slough Retail Park, 1.5 miles north of Eton, are typical of where shop-fit joints, frontages and staff areas need neat, colour-matched sealant. Sites a few miles apart, such as Slough Retail Park and Portland Business Park, can share one programme and one point of contact.

How the job changes by surface
Hotel interiors
Hotels use colour-matched sealant in bathrooms, bedrooms and public areas. Wet-area sealants come in colours other than white too, including shades for tiled and stone bathrooms.
Natural stone
Stone has variation, so the aim is a colour that sits naturally against it. A stone-safe neutral-cure product is used.
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Colour variation across natural stone or brick that no single shade can match
- Repairing damaged frames or cladding
- Overpainting a joint that needs a non-paintable product
If in doubt, phone 01277 525 020 or email a schedule or drawings and we’ll say what we think.
Where we work in Eton
- Powder-coated and anodised frames
- Hotel bathrooms and public areas
- Cladding panels
- Shop-fit joinery and counters
- Natural stone and brick
- Office fit-out finishes
Why act early in Eton
Agreeing the colour before work starts avoids paying twice. A sample takes little time compared with replacing joints in the wrong colour. Halls, stores and units around places like Eton may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. If others near Eton need work, visits can be combined. A fixed quote is given before anything starts.
- We confirm the joint type and the product it needs.
- Your RAL reference, sample or photo is checked against that product’s colours.
- The nearest colour is agreed, with a sample bead where needed.
- We cut out the existing bead, clean and set the depth.
- Edges are masked and the coloured sealant applied and tooled.
- Masking comes off and the work is checked with you.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Tell us what induction or permit system the site runs
- Arrange parking or a loading space
