Facade sealing around Eltham: points for this area
As part of Greater London, Eltham 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. Eltham has several hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Building work at universities like University of Greenwich - Avery Hill, 0.9 miles east of Eltham, is often timed for the summer, mastic included. New units and refits on sites such as Green Lane Business Park, 0.7 miles south-east of Eltham, need their panel and perimeter joints sealed to the specification.
Eltham is about 7 miles west of Dartford, in Greater London. Our applicators travel to Eltham for work on facade joints, handled exactly as we handle every other area. Our Greater London coverage takes in 764 places. Sites around London have their own page, roughly 8 miles from Eltham.
Anyone looking for facade sealing in SE9, SE12, DA15 and BR7 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

How we handle facade sealing in Eltham
Managing agents and owners in Eltham ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. Most enquiries involve gaps between rainscreen or cladding panels and draughts around frames and panels, across cladding panel joints, window and door perimeters and perimeter joints where frames meet the structure. Searching for sealant specialists in Eltham? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Construction in a London area such as Eltham means working on constrained sites: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
Every job we finish is backed by a 12-month workmanship guarantee, in Eltham as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Common problems we fix in Eltham
Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead.
What tends to prompt an enquiry:
- Sealant pulling away from frames or panels
- Patch repairs that keep failing
- Draughts around frames and panels
- Discoloured or dirty facade joints
Extensions at sites like Eltham Community Hospital (under half a mile north of Eltham) normally sit beside working departments, and the mastic follows strict access rules.

From enquiry to sign-off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. All of Greater London is in the ULEZ, and kerbside space in Eltham can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- 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.
- The completed runs are checked with you, then the 12-month guarantee applies.
Preparing the site
- Have the specification and drawings to hand
- Send your site hours and access windows
- Tell us which areas need to stay in use

Honest limits
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Cracked or spalling substrates that need repair before sealing
- Replacing glass or failed glazing units
- Joints too narrow for the movement they take, which need redesign
If you are not sure, just ring 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
Surfaces we seal
- Shopfront frames
- Perimeter joints where frames meet the structure
- Cladding panel joints
- Stone and brick facade joints
- Window and door perimeters
- Coping and flashing joints
Common questions from Eltham clients
Is a hospital such as Eltham Community Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough
How much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.
Do you use silicone for external joints?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others.
Is it okay to overlay old mastic?
No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.
Will you check whether the sealant is causing the leak?
Yes. Photos help, and you can call the office on 01277 525 020 or email a schedule or drawings to arrange a visit. Many frame leaks are sealant failures, though not all, and we will be honest about which it is.
Do you offer coloured sealant?
That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
How the job changes by surface
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints rather than the system it surrounds.
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone, with primer where its maker specifies.

Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Combine resealing with other works that need access
- Note when each elevation was last resealed
- Keep sills, gutters and drainage paths clear
- Don’t wait for a second leak before calling
Keep a note of which product went in and when. Future work can then match the product and colour without guesswork.
Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones.
