Construction mastic across Codmore Hill
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
After the work
Once the work is signed off, a little attention goes a long way:
- Don’t schedule sealing before decorators and flooring are done
- Ask installers to correct oversized gaps first
- Keep product details for future maintenance
- Don’t force external sealing on a damp or frosty day
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known. Tell us what records you need and we will confirm with the quote.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, leaving the remedial work to the contractor. Getting the product and preparation right first time avoids that.
About our construction mastic in Codmore Hill
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member, and we are fully insured. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. If you have snag items on joints that need redoing before handover and perimeter gaps outside the sealant’s range, we can help, on window and door perimeters, internal decorators’ caulk and cladding and panel joints alike. One point of contact handles commercial sealant work in Codmore Hill from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Sites around smaller places like Codmore Hill can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs and the programme let us give a fixed quote.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Common problems we fix in Codmore Hill
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We stick to the specified product, or put any alternative to you first.
Clients typically get in touch after noticing one or more of the following:
- Sanitary sealant damaged by following trades
- A mastic package split between trades with no clear owner
- Window and door perimeters that won’t pass inspection
- Existing joints on a refurb that need cutting out and resealing
Hotels like Chequers Hotel (to the south-west of Codmore Hill) rarely close for long, so refurbishment mastic is phased floor by floor.
What to look for in a quote
- Who will actually carry out the work
- Their pre-qualification and accreditations
- Whether old or failed sealant will be cut out, not overlaid
- How long is the guarantee, and what does it include?
How the job changes by surface
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. We set the depth with backing rod to avoid three-sided adhesion.
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control; we work to the specification and the manufacturer’s installation guidance.

Common questions from Codmore Hill clients
Is a smaller place like Codmore Hill outside your area?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work at a site such as Broomers Hill Business Park, by Codmore Hill?
Yes. Our area takes in Codmore Hill and its surroundings, with estates and business parks such as Broomers Hill Business Park included. Photos and a short description are enough for a first look.
What joints do you seal on a new build?
External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. We price to the specification and drawings.
Do you use the sealant named in the specification?
The specified product is what goes in. If we think an alternative would suit better, we put it to you first.
Do you do fire-rated sealing on new builds?
Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. The design and sign-off belong to the designer, fire engineer or building control.
Do you take on mastic snagging only?
Yes. Share the list and photographs, and a fixed quote follows, then clear it to your programme.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Cost factors for mastic packages
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Location, for remote and island sites
- Which sealant the job calls for
- Quantities, in metres or numbers
- Induction, permit and paperwork requirements
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Details that help us quote
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- The site address and postcode
- Asbestos survey details if the building is older
- Clear photos of the problem areas
- Any dates the work must fit around
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or send photos by email.
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Codmore Hill, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.
- We price from the drawings, specification and programme you send.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.

Why act early in Codmore Hill
When a package runs over budget, downgrading the product is a common first thought. A failed joint in the defects period costs far more than the product difference. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Around Codmore Hill, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
Why us?
- Our applicators hold CSCS cards
- Colours confirmed for the specified product
- Work to your specification and the manufacturer’s guidance
- One number for every site we cover

Facades, frames and programmes in Codmore Hill
At about 40 miles from central London, Codmore Hill is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.
With historic properties like Old Place Manor, 1 mile to the south-west of Codmore Hill, in the area, refurbishment work often meets old masonry that needs compatible sealants. For contractors at a school such as St Mary's Church of England Primary School, sealing has to be finished before term starts.
