For managing agents and facilities managers
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Hayes. Several sites can go on one quote, which keeps the paperwork simple.
Construction mastic in Hayes
Buyers, tenants and clients notice sealant lines long before they notice the structure. A smeared bead round a window or a gap behind a worktop ends up on the snag list and clearing them late eats into the handover window. We seal so the snag list stays short, area by area through the programme. Most enquiries involve snag items on joints that need redoing before handover and frame gaps too wide for sealant alone, on internal decorators’ caulk, brick and block movement joints and cladding and panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Hayes, preparation and product choice get the time they need.
Around Hayes, as across London, much of the work is refurbishing existing buildings as well as building new ones. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Quoting for work in Hayes
The price varies from site to site. It mainly depends on:
- Specialist products, such as fire-rated or hygienic sealants
- How accessible the joints are
- Distance, for remote addresses
- Working within restricted access windows
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Access details, including height
- The product your specification calls for
- Rough lengths or quantities, or drawings if you have them
- A wide shot and a close-up of the area
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Ask installers to correct oversized gaps first
- Ask cleaners to use soft cloths around fresh sealant
- Allow flexibility for external sealing in damp or cold weather
- Brief following trades on areas that have been sealed
If a joint is damaged after sealing, flag it early. Snags can be picked up in a planned close-out visit as agreed in the quote.
Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors. Getting the product and preparation right first time avoids that.
Common questions from Hayes clients
Is hospital work, at somewhere like Hillingdon Hospital, something you do?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Could you schedule work at a campus like Brunel University of London for the vacation?
Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Will you stick to the specified products?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Do you install fire-rated sealant as part of a package?
Where it’s specified, yes, working to the specification and the manufacturer’s installation guidance. If the detail calls for collars, wraps or batts instead, we will tell you.
Building and refurbishing in Hayes
Site traffic in Hayes falls within London’s ULEZ, like everywhere else in Greater London. Deliveries are booked and storage is tight, so mastic materials come in as needed. Hayes has a good number of hotels close by, all within 2 miles. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
Work at a hotel such as Fountain House Hotel, less than half a mile north-east of Hayes, tends to be programmed around bookings, mastic included. For contractors on a campus like Brunel University of London, 2.6 miles to the north-west of Hayes, facade and perimeter sealing has to fit around students and term dates. When units on a site such as Caxton Trading Estate (to the south of Hayes) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Hayes is about 8 miles east of Slough, in Greater London. Across the UB3 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Greater London coverage takes in 764 places, large and small. For work in that direction, see our London page, about 14 miles away.
Commercial sites across UB3, UB4, UB8 and UB10 are covered. Among the streets we cover are Church Road, Drenon Square and Townfield Square. With the A312 nearby, Hayes is easy to get to with materials and equipment. We also cover Hillingdon (2 miles north-west), Yiewsley (2 miles west), West Drayton (2 miles west), Cowley (3 miles west) and Uxbridge (3 miles north-west). Bigger towns within reach include London (14 miles east), City of Westminster (12 miles east), Marylebone (12 miles east), Kensington (9 miles east), St Pancras (13 miles east) and Shoreditch (15 miles east).
Around Hayes
We work on buildings around Dr Triplett's CofE Primary School, Rosedale College and Barra Hall Park, among other places. Hayes’s nearest station is Hayes & Harlington station, about 0.9 miles south of the centre. Nearby you’ll also find Hillingdon Museum and Archives Services (3.2 miles north-west) and Hayes Cottage Hospital (under half a mile north). Green spaces nearby include Middle Lake and Yeading Brook Meadows.
Why act early in Hayes
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. A single mastic package gives one point of responsibility. In Hayes, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Specifying the product where the designer hasn’t
- Frames fitted out of tolerance
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Internal decorators’ caulk
- Window and door perimeters
- Floor and skirting junctions
- Cladding and panel joints
- Sanitary and kitchen joints
- Brick and block movement joints
From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a job in Hayes, access comes first. Give us the hours we can be on site and we will schedule to suit.
- First we take quantities off the drawings and read through the specification.
- You receive a fixed quote listing scope, products and phasing.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- We seal each plot or floor as it’s released to us.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
