Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
From enquiry to sign-off
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, then handed back before the next one starts. Planning a London job such as one in Cudham starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- Site photos, drawings or a visit tell us what’s there and how it has failed.
- You get a fixed quote covering removal, preparation and the new sealant.
- Sequence, access and working times are settled before the first joint is touched.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- Completed areas are signed off with you under our 12-month guarantee.
Before we start on site
- Arrange parking or a loading space
- Clear stock, furniture or equipment away from the joints
- Tell us which areas need to stay in use

Sealant specialists in Cudham
Sealant joints are easy to overlook until one lets water in, and on a working site that normally surfaces as a leak, a stain or a complaint from occupiers. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. If you are dealing with external beads that have gone brittle and cracked and shrunken sealant along kitchen worktops and splashbacks, we can help. Looking for mastic applicators who cover Cudham? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
A lot of what we do in Cudham is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
Around Cudham, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, so one job can involve stone, brick, powder-coated frames and laminate in a single visit. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When it isn’t the sealant
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Roof leaks that only look like a joint problem
- Broken glass or blown double-glazed units
- Structural cracks or movement the joints weren’t designed for
If you are not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer.
Joints and surfaces we work on

Questions about Cudham
Does your area include sites such as Biggin Hill Airport Trading Estate, near Cudham?
Yes, sites like Biggin Hill Airport Trading Estate are within our area, along with the rest of Cudham. To start, just call 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Can you cope with the access rules in a London building?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry.
What do you need from us to quote?
Send photographs, drawings or a list of locations through our quote form. If a visit is needed we’ll book one, and a fixed quote follows.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Could the old sealant in an older building contain asbestos?
We check the asbestos register or survey before any old sealant is disturbed. Managing asbestos is the dutyholder’s responsibility and removing it isn’t something we do.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Do you work directly for building managers?
Yes. You can send details through our quote form, and tell us what site paperwork you need.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Brief cleaning contractors to avoid scourers and blades on sealant
- Keep washroom and kitchen extraction working
- Check sealant as part of routine building inspections
- Ask fit-out and M&E contractors to report any sealant they disturb
We stand behind the workmanship with a 12-month guarantee. File the handover note with the building records.
Sealant rarely fails all at once across a building. The first failures are often a warning about the rest so the whole run is worth inspecting. We will tell you which sealant joints need doing first and which can wait.
When to bring in a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
How the quote is worked out
To price the job, we consider:
- Travel to remote or island sites
- Whether old sealant has to be cut out first
- The size and state of each joint
- How much there is to seal
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
Sending details for a quote
However big the job, these details speed things up:
- The site address and postcode
- Drawings or a marked-up plan, if available
- The product your specification calls for
- Clear photos of the problem areas
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
Shops, offices and hotels in and around Cudham
Two named trading, business or retail sites lie within about 3 miles of Cudham. Each new occupier on a park like these tends to refit, from reception to staff kitchen, often in a colour the occupier specifies. London premises usually come with a building manager, booked loading and house rules for contractors. We fit into those systems and phase the work so the building keeps operating.
Shops and cafés around stations like Chelsfield station, 3.1 miles to the north-east of Cudham, trade from early, so work is timed around them. Access in Cudham needs thought: the ULEZ covers all of Greater London, and loading and parking are rarely simple. Trade counters and showrooms on estates such as Biggin Hill Airport Trading Estate, 1.8 miles west of Cudham, need neat joints where customers see them.

Why it’s worth doing now in Cudham
Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. Often the fitting is sound and the joint is the only thing letting it down. A careful reseal is a far smaller undertaking than replacement. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
