Work for main contractors and building owners
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
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.
Construction mastic for commercial buildings in Chenies
Mastic is often where a new building first shows its quality to the client. 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, whatever the size of the scheme. We work on sanitary and kitchen joints, floor and skirting junctions and cladding and panel joints, and the failures we are asked to look at most are cracks opening in caulked internal joints and different trades sealing to different standards. One point of contact handles commercial sealant work in Chenies from the first photographs to the final walk-round, whether it’s one building or several.
For a site near Chenies, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photos and the programme and we will quote to suit.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

After the work
Regular inspection catches problems early. Specifically:
- Keep scrapers and abrasive pads off new beads
- Keep product details for future maintenance
- Don’t force external sealing on a damp or frosty day
- Check frame gaps are within the sealant’s range before sealing
Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean so keep them off the joints.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Holding off until conditions suit avoids callbacks, so we plan external work with that in mind.
Why it’s worth doing now in Chenies
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal. We will say so if a frame itself is the problem. Older rural buildings around Chenies move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Cost factors for mastic packages
These are the things that shape the price:
- How much existing material needs removing
- Induction, permit and paperwork requirements
- Distance, for remote addresses
- Specialist products, such as fire-rated or hygienic sealants
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Sending details for a quote
We can often quote from photographs and a few details. It helps to include:
- The product your specification calls for
- Access details, including height
- Any dates the work must fit around
- What the building is and how it’s used
For a fixed quote, call the office on 01277 525 020 or send details through our quote form, telling us the site location and the nature of the job. Our quote form is another easy route.
Places near Chenies
What else we do in Chenies
Construction mastic in Chenies: the local picture
There are a number of hotels within about 2 miles of Chenies. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.
For contractors at a school such as Chenies School, sealing has to be finished before term starts. On a healthcare site such as Amersham Hospital, which lies west of Chenies, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For contractors on a campus like Buckinghamshire New University, which lies west of Chenies, facade and perimeter sealing has to fit around students and term dates.
Chenies is about 3 miles east of Amersham, in Buckinghamshire. We send applicators to Chenies for mastic packages. 308 places across Buckinghamshire fall within our area, including Chenies. We also cover London, some 22 miles away.

We also cover Latimer (1 mile west), Flaunden (1 mile north), Little Chalfont (2 miles west), Belsize (2 miles north-east) and Chorleywood (2 miles south-east).

Common questions from Chenies clients
Is Chenies off your patch?
No. Places such as Chenies are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you work on a hospital site such as Amersham Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Do you guarantee new-build sealant work?
Our workmanship carries a 12-month guarantee from sign-off. Damage by others after we’ve finished isn’t covered.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Will you stick to the specified products?
We use the product the specification names. Any suggested alternative is put to you before anything changes.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
How do you work with the site programme?
We seal plot by plot or floor by floor as areas are released. The sequence is settled with your site team.
From enquiry to sign-off
Occupied buildings need a little choreography. 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. Jobs in and around smaller places like Chenies are usually planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
What we need from you
- Share the asbestos register for older buildings
- Tell us what induction or permit system the site runs
- Confirm the product named in the specification
Quotes
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
Advice
Honest limits
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Joint design decisions that belong to the architect or engineer
- Frames fitted out of tolerance
- Rework caused by others damaging completed areas
If you are not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer.
