Need facade sealing in Addiscombe?
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Should maintenance staff do it?
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.
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.
Facade sealing for commercial buildings in Addiscombe
External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. Site teams most often ask us about hard, chalky sealant that no longer flexes and draughts around frames and panels, across perimeter joints where frames meet the structure, shopfront frames and stone and brick facade joints. Searching for sealant specialists in Addiscombe? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Addiscombe must meet its standards or pay the daily charge. Alongside that, sites usually need booked deliveries and a plan for where materials go.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

What happens if it’s left?
If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice. In Addiscombe, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.

Our process
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
What we need from you
- Flag any permit to work we will need
- Share your working hours and any access restrictions
- Tell staff and tenants when we will be in
Quotes
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
Advice
What we can’t put right
Being straight saves everyone time. New sealant won’t cure:
- Water getting in through cracked render or porous masonry
- Arranging specialist high-level access, which is planned with the client
- Work on the window or framing system itself
If you are not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Ask about asbestos in pre-2000 mastic
- Walk the elevations once or twice a year
- Note when each elevation was last resealed
- Insist on a full cut-out when joints are renewed
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.
Facade sealing in Addiscombe: the local picture
The area within 2 miles of Addiscombe holds plenty of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. As part of Greater London, Addiscombe is inside the ULEZ, which applies to every van on site. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
Work at a hotel such as Croydon Park Hotel, 1.2 miles south-west of Addiscombe, tends to be programmed around bookings, mastic included. School extensions, at buildings such as Oasis Academy Shirley Park, normally run to the summer holidays, mastic included. On a healthcare site such as Shirley Oaks Hospital, under half a mile east of Addiscombe, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Questions about Addiscombe
Can you work around term dates at a campus such as Croydon College?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Will you take on work at estates like Chaffinch Business Park, close to Addiscombe?
Yes. Our area takes in Addiscombe and its surroundings, with estates and business parks such as Chaffinch Business Park included. Send details of the unit and the work through our quote form for a quick quote.
Do you use silicone for external joints?
It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Can you look at water coming in around a frame?
Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all.
Do you provide access for facade work?
Access is planned with you before we quote. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and the quote will reflect it.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Cost factors for facade joints
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Induction, permit and paperwork requirements
- Which sealant the job calls for
- Distance, for remote addresses
- Any access equipment needed
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Whether it’s one area or a whole building, these details speed things up:
