Construction mastic for Cold Christmas sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Different surfaces, different methods
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. A single team keeps the standard consistent, plot by plot or floor by floor.
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s for gaps that stay still and get painted, and we use a flexible sealant where there’s movement.
Construction mastic in Cold Christmas, done properly
On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old. New and existing joints then get the same preparation. We work on floor and skirting junctions, window and door perimeters and sanitary and kitchen joints, and the usual reasons a site gets in touch are new external sealant already peeling away and old sealant on a refurbishment that needs stripping before new work. A single leaking joint is often how a building in Cold Christmas first comes to us: we look at the rest while we’re there and tell you what we find.
Around smaller places like Cold Christmas, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Your questions answered
Is Cold Christmas too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Will you plan work around the academic year at somewhere like Hertford College: Ware Campus?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.
What site paperwork can you supply?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Can you work while the building is occupied?
In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Do you do fire-rated sealing on new builds?
It can be part of the package where specified. Tell us what records you need and we will confirm with the quote.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
How soon can the area be used again?
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.
Construction mastic in Cold Christmas: the local picture
Cold Christmas is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team. Cold Christmas has a number of hotels close by, all within 2 miles. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.
New units and refits on sites such as Thundridge Business Park, 1 mile to the west of Cold Christmas, need their panel and perimeter joints sealed to the specification. Projects at colleges like Hertford College: Ware Campus (2.2 miles south-west of Cold Christmas) tend to run to term dates, so the mastic is planned tightly. Projects at schools like Thundridge Church of England Primary School work to term dates, so mastic is programmed tightly.
Cold Christmas is about 2 miles north-east of Ware, in Hertfordshire.

What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Damage to finishes by other trades after we have sealed
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Frames fitted out of tolerance
If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think before you book.

On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Rural sites near Cold Christmas may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Each area is sealed when it’s released.
- Every joint is cleaned, set to depth and sealed with the specified product.

What sets the cost
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Quantities, in metres or numbers
- Whether old sealant has to be cut out first
- Any access equipment needed
- Induction, permit and paperwork requirements
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What we need to price the job
Good information means a firmer quote. Helpful details to send:
- How the joints are reached, and at what height
- Where the site is, with the postcode
- Whether an asbestos survey exists
- The type of building and who uses it
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or use the quote form with what you know.
Looking after the joints
Regular inspection catches problems early. Specifically:
- Don’t schedule sealing before decorators and flooring are done
- Allow flexibility for external sealing in damp or cold weather
- Get the mastic subcontractor involved early in the programme
- Note which sealant went where at handover
If a joint is damaged after sealing, flag it early. Snags can be picked up in a planned close-out visit, priced as part of the package or separately.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure, so the installer needs to correct it first. We flag them as soon as we see them.
For managing agents and facilities managers
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
