About our facade sealing in Addington
Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range. We plan for that and keep you updated. If you’re dealing with draughts around frames and panels and patch repairs that keep failing, we can put it right, whatever the surface. Searching for sealant specialists in Addington? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Addington must meet its standards or pay the daily charge. Alongside that, sites typically need booked deliveries and a plan for where materials go.
Every job we finish is backed by a 12-month workmanship guarantee, in Addington as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the job changes by surface
Window and door perimeters
Frame materials vary, and so does the preparation. We clean and prime to the sealant maker’s guidance for each surface.
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.

From enquiry to sign-off
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We start with photos, drawings or a visit to see the joints and agree access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and both faces cleaned back.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
What we need from you
- Let building users know which areas are affected
- Send any specification or drawings in advance
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Quoting for work in Addington
Before we quote, we look at:
- Removal of failed or old sealant
- Induction, permit and paperwork requirements
- Location, for remote and island sites
- The product specified
Pricing facade joints depends on quantities, condition and access, and any specification that applies. Call for a quote.
Details that help us quote
It doesn’t need to be a full survey. These details are enough to start:
- Photos of the joints, close up and from further back
- How the joints are reached, and at what height
- Drawings or a marked-up plan, if available
- Asbestos survey details if the building is older
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Keeping the joints sound
To get the most from the new sealant:
- Keep pressure washers away from fresh sealant
- Never let anyone seal over old sealant
- Share access with other external trades
- Ask about asbestos in pre-2000 mastic
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards using a matching sealant.
Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in.
Commercial clients in Addington
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Your questions answered
Would you work within a site like Bethlem Royal Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Can you work around term dates at a campus such as John Ruskin College?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Is old mastic on our building likely to contain asbestos?
In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Can you just add new sealant on top?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely. That is what makes the new joint last.
How much does the work cost?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we’ll price it properly.
Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Specialist high-level access methods
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Replacing glass or failed glazing units
If in doubt, call the office on 01277 525 020 or send photos by email and we will say what we think before you book.
Surfaces we seal
- Cladding panel joints
- Window and door perimeters
- Shopfront frames
- Coping and flashing joints
- Stone and brick facade joints
- Perimeter joints where frames meet the structure
Facades, frames and programmes in Addington
Addington has several hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. As part of Greater London, Addington is inside the ULEZ, which applies to every van on site. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
For contractors at a school such as Applegarth Academy, sealing has to be finished before term starts. Older buildings in the area around Addington, such as Addington Palace (0.4 miles west of Addington), need care when sealed: the product has to suit soft or historic materials. For contractors at a college like John Ruskin College, which lies south-west of Addington, perimeters and internal sealant are timed for the holidays.
