Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
About our coloured sealant in Middlegreen
Colour is often written into the specification, by RAL reference or by matching a sample. Standard sealant ranges cover many colours, so we check what the specified product is made in. An exact bespoke match can’t always be promised, so we talk you through the nearest colours. If you’re dealing with stained or mouldy coloured joints in washrooms and old sealant that has yellowed, darkened or faded, we can put it right. Most enquiries from Middlegreen 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.
Commercial sealant work around smaller places like Middlegreen tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Paintable products in joints they aren’t suited to
- A colour that never alters with age
- Restoring stained stone or masonry next to old sealant
If you are not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer.

Coloured sealant in Middlegreen: the local picture
The area within 2 miles of Middlegreen holds plenty of hotels. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet, with rooms done in turn while the rest stay let. Middlegreen has at least three named business or industrial parks inside a 3-mile radius. Sites like these see regular refits, with shopfronts, offices and staff areas to seal, often in a colour the occupier specifies.
In hotels such as Skyways Hotel, 0.8 miles south-west of Middlegreen, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. Shopping centres and retail parks such as Slough Retail Park, 2.8 miles west of Middlegreen, see a steady turnover of shop fits, each leaving joints where colour and finish matter.
Middlegreen is about 2 miles east of Slough, in Buckinghamshire. Across the SL3 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Buckinghamshire, 308 places are covered, Middlegreen among them. Reading is covered too, around 19 miles from Middlegreen.

Different surfaces, different methods
Cladding panels
Panel joints form a grid on the facade, so colour matters. The colour is picked from the range of a sealant that suits the panel joint.
Powder-coated and anodised frames
Window, door and shopfront frames in RAL colours often need a sealant to suit. The frame colour is checked against what the product is made in.

When to call us in Middlegreen
A change of finish can leave existing sealant mismatched. New cladding colours, repainted frames or a refreshed shop fit all prompt colour changes, and the joints need to match.
These are often picked up first by site or facilities staff:
- Old colour-matched joints lifting at the edges
- Colour changes after a rebrand or refit
- Previous reseals that don’t match the original
- Shop fits that need consistent sealant colours across sites
A unit on an estate like Deseronto Trading Estate (to the south-east of Middlegreen) normally has an office front, a trade counter and staff facilities with joints of their own.

What happens if it’s left?
People notice sealant lines more than you might expect, particularly on high-end finishes. Resealing in a suitable colour is a modest cost against the finishes it sits beside, and it lifts the whole area. One visit to deal with every failing joint makes more sense than several trips to a place like Middlegreen. Photos of every joint help us quote for the whole job.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off.

Advice
Your questions answered
Is Middlegreen too far out for you?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do hotels near Middlegreen have to close for sealant work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email the details over. Include photographs or drawings if you have them.
Do you do a sample bead?
Yes. Tell us who approves colour and we’ll plan the sample into the programme before the main run.
How long does a job like this take?
That varies with the scale of the job, though a typical visit usually takes about the same time as any other sealant work, plus a little longer if a sample bead is agreed first. For bigger or phased jobs, we’ll set out a timescale with the quote.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
