Facade sealing in New Addington
Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits. We plan for that and keep you updated. Site teams most often ask us about water coming in around window frames and discoloured or dirty facade joints, across perimeter joints where frames meet the structure, cladding panel joints and stone and brick facade joints. Facilities teams, main contractors and managing agents in New Addington tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
A 12-month guarantee applies to all our work in Greater London. Should something we installed fail, ring 01277 525 020 or email us and we’ll come back to it.

Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Record the product and colour used on each elevation
- Inspect facade joints on a regular cycle
- Combine resealing with other works that need access
- Investigate damp beside windows promptly
Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed instead of soaking the joints.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading.
How the quote is worked out
Quotes vary with the job. It mainly depends on:
- The product specified
- How much there is to seal
- Whether old sealant has to be cut out first
- Travel to remote or island sites
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- Rough lengths or quantities, or drawings if you have them
- The type of building and who uses it
- Access details, including height
- Asbestos survey details if the building is older
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Common questions from New Addington clients
Does your area include sites such as Vulcan Way Industrial Estate, near New Addington?
Yes. Our area takes in New Addington and its surroundings, with estates and business parks such as Vulcan Way Industrial Estate included. A few photos and the unit address let us price the work.
Will you plan work around the academic year at somewhere like John Ruskin College?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
What will the job cost?
There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Leave it or put it right?
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, often turning up far from the joint. In New Addington, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
Why appoint us

Our process
Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. 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.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Before we start on site
- Warn occupants and staff about the work
- Confirm the product named in the specification
- Tell us what induction or permit system the site runs

Do you need facade sealing in New Addington?
When the sealant tears down its centre, it has usually been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
These are often picked up first by site or facilities staff:
- Perimeter joints where frames meet the structure
- New sealant peeling off old mastic
- Failed sealant on precast panel joints
- Draughts around frames and panels
Further education sites such as John Ruskin College, 1.3 miles north-west of New Addington, are extended and refurbished from time to time, with mastic often programmed into the summer break.

Facade sealing around New Addington: what changes locally
As part of Greater London, New Addington is inside the ULEZ, which applies to every van on site. Delivery slots and scarce storage shape how and when the mastic goes in. Several hotels sit less than 2 miles from New Addington. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Historic houses such as Addington Palace, 1.5 miles north-west of New Addington, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. New units and refits on sites such as Vulcan Way Industrial Estate (to the east of New Addington) need their panel and perimeter joints sealed to the specification.

What else we do in New Addington
General trades versus a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
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.
