Advice
Mastic sealing in Colgate, done properly
For blocks and buildings in Colgate and across West Sussex, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. Most enquiries involve complaints coming in block by block and worn sealant at communal door frames, across communal entrances and stairwells, communal kitchens and washrooms and shopfronts below residential blocks. A specialist sealant contractor works differently from a general builder: on jobs in Colgate, preparation and product choice get the time they need.
Around smaller places like Colgate, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What else we do in Colgate
Do you need mastic sealing in Colgate?
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Regular cleaning wears them further.
Look out for the following:
- Window mastic that has split and shrunk
- Old repairs sealed over failed mastic
- The same joint failures repeated across a portfolio
- Leaks at window and door perimeters
Historic properties like Tyes Place, 4.5 miles south-east of Colgate, show the age of some local stock, where frame mastic must suit soft brick or stone.

Looking after buildings in and around Colgate
Colgate is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first. Colgate has two care or nursing homes no more than 2 miles away. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents.
For owners of several units at places like Holmbush Potteries Industrial Estate, 1 mile to the north of Colgate, one programme can deal with frame and external mastic across the lot. Churches, halls and community buildings such as St. Saviour's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Colgate is about 3 miles south-west of Crawley, in West Sussex. Anywhere in RH13, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

Surface by surface
Communal areas
Low-level communal joints get damaged more than most, so they often need renewing sooner.
Window and door perimeters on blocks
Blocks have a mix of frame materials, so the grade we pick has to bond to frame and wall alike. Colours are confirmed for the product used.
Work for main contractors and building owners
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.
Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Questions about Colgate
Can you work in a care home near Colgate with residents in?
Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.
Is Colgate too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Masonry that has broken away beside the joint
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we will tell you honestly.
