Mastic sealing for commercial buildings in Chaldon
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable. We will confirm the colours available for the specified product. If you have leaks at window and door perimeters and mastic failing across several blocks on an estate, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Chaldon, preparation and product choice get the time they need.
Around smaller places like Chaldon, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

From enquiry to sign-off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a few days for most blocks, with larger programmes scheduled building by building, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Chaldon are normally planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready
- Warn occupants and staff about the work
- Let us know about inductions and permits
- Agree which areas must stay open
Getting a fixed quote
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Advice
Why it’s worth doing now in Chaldon
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Halls, stores and units around places like Chaldon may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What we’re called out for in Chaldon
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone, so these repairs rarely last.
If one of these sounds familiar, it’s time for a closer look:
- Failed external movement joints
- Damaged joints in communal entrances and corridors
- Draught complaints from residents or tenants
- Patchy repairs in mismatched sealant
Landlords with units on estates such as Church Walk Shopping Centre (to the east of Chaldon) can bring frame, door and external mastic across several units into one programme.
What to look for in a quote
- Will failed sealant be removed rather than covered?
- How joint depth will be controlled
- Whether primer will be used where the manufacturer specifies it
- Will CSCS-carded applicators be on site?
Different surfaces, different methods
Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Regular inspection is the best way to plan resealing.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
FAQs: Chaldon
Do you cover business parks and estates near Chaldon, such as Church Walk Shopping Centre?
Yes. We cover Chaldon and the area around it, including industrial estates, business parks and retail parks such as Church Walk Shopping Centre. Photos and a short description are enough for a first look.
Do you work for managing agents with blocks near Caterham station?

Do you cover Chaldon?
Yes. Sites across Chaldon are covered, and the same phone number covers every area.
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.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
How do you reach windows on upper floors?
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’ll confirm the approach in the quote.
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Avoid piecemeal callouts where you can
- Ask residents or tenants to report leaks and draughts early
- Include mastic in your cyclical inspections
- Keep bins and bikes away from communal door frames
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
What else we do in Chaldon
Looking after buildings in and around Chaldon
Chaldon sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first. There are three care or nursing homes within about 2 miles of Chaldon. Care home owners need frame and external mastic kept sound without unsettling residents.
If you are responsible for a building such as Church of St Peter and St Paul, frame and door mastic needs the same attention as any other property. Site managers at schools like St Peter and St Paul CofE Infant School can fit frame mastic into the summer works.
