What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Damage to finishes by other trades after we have sealed
- Specifying the product where the designer hasn’t
- Frames fitted out of tolerance
If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think before you book.
Surfaces we seal
- Cladding and panel joints
- Internal decorators’ caulk
- Brick and block movement joints
- Window and door perimeters
- Sanitary and kitchen joints
- Floor and skirting junctions
About our construction mastic in Catmore
Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility, and one applicator team gives a consistent finish. The enquiries we see most involve oversized or tapered gaps around new frames and external joints sealed in damp or cold conditions that are now failing, across cladding and panel joints, brick and block movement joints and sanitary and kitchen joints. One point of contact handles commercial sealant work in Catmore from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Conversions of older rural buildings near smaller places such as Catmore bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Our process
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. Smaller jobs around Catmore can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised straight away.
- Final snagging is completed and the 12-month guarantee applies.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Flag any permit to work we will need
- Send asbestos survey details if the building is pre-2000
Get a fixed quote
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 email a schedule or drawings with what you know.

Questions we are asked in Catmore
Which documents can you supply for work in Catmore?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Can the mastic package for our job in Catmore follow the site programme?
Yes, we work to the programme and the sequence the site sets. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Do your applicators hold CSCS cards?
We’re CHAS accredited and a Constructionline member, and each applicator is CSCS-carded. We’re fully insured for public liability.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Do you offer coloured sealant?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Why act early in Catmore
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. Converted and older buildings near places like Catmore tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you are ready.

Signs you need construction mastic in Catmore
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly so we set the depth properly before sealing.
Any of the following is a good reason to get the joints checked over:
- Sealant knocked or painted over by other trades
- Snag items on joints that need redoing before handover
- Internal caulk splitting as the building dries out
- Missed perimeter joints on a new elevation
On any site in or around Catmore, the mastic follows the specification and the programme.
Questions to ask before you book
- Will RAMS and insurance details be available?
- What the guarantee covers, and for how long
- Do they follow the manufacturer’s priming guidance?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Looking after the joints
To get the most from the new sealant:
- Use the product the specification names
- Keep scrapers and abrasive pads off new beads
- Brief following trades on areas that have been sealed
- Release areas for mastic once other trades have finished in them
The package carries our 12-month guarantee for workmanship. The guarantee covers how we sealed, not later damage by other trades, so protecting sealed areas matters.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks, so we plan external work with that in mind.

Construction mastic in Catmore: the local picture
Catmore lies roughly 54 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. Catmore sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.
A facade joint near Catmore lasts when width, depth and backing are right, not just the finish.
