What Penge’s businesses ask us to seal
Contractor rules in London buildings can be strict, with inductions, permits and timed loading all normal. We fit into those systems and phase the work so the building keeps operating. The 2 miles around Penge include four care or nursing homes. Care settings have kitchens, lounges and corridors where joints need to be neat and easy to clean.
On estates like Franklin Industrial Estate, which lies south-east of Penge, the office and welfare end of each unit has its own sealant to maintain. Offices and shops close to stations such as Penge West station, under half a mile north of Penge, tend to be busy all day, so sealant work is planned around opening hours.

Sealant specialists in Penge
On a commercial site, sealant turns up in more places than people expect: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Externally it keeps rain out of frame perimeters, panel joints and movement joints. We deal with internal and external sealant joints alike, picking the product for each location rather than one tube for everything. If you have external beads that have gone brittle and cracked and gaps behind commercial kitchen worktops and sinks, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Penge it comes down to the same thing: the right product in a properly prepared joint.
If you look after more than one building near Penge, the work can be planned as one programme, so standards and paperwork match across every site.
Buildings in a London area such as Penge rarely close for maintenance: occupied offices, ground-floor retail under residential floors and busy shared entrances. Work is split into zones agreed with the building or facilities manager, so the premises keep working around us.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

FAQs: Penge
Can you work at a site such as Franklin Industrial Estate, by Penge?
Yes. Estates, retail parks and business parks around Penge, Franklin Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.
Will our hotel in Penge need to close for the work?
Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
How long does a typical visit take?
That varies with the scale of the job, but the work typically takes anything from part of a day on a short run of joints to several weeks on a large phased package. Larger or phased jobs take longer, and we will give you a timescale with the quote.
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.
Can areas stay open during the work?
It’s mostly about sequence: we agree access windows, phase the work and keep enough facilities open. Tell us what has to stay open and we’ll plan the job around it.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Why it’s worth doing now in Penge
It can be tempting to hold sealant work back until the next refurbishment. For internal joints that are only cosmetic, that can make sense, but external and wet-area joints that already leak shouldn’t wait. We can seal the urgent joints now and leave the rest for the programme. Getting scaffold, permits or access booked in Penge takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Why us?
- A Constructionline member, so easy to vet
- 12 months’ guarantee on every job
- Fully insured, including public liability cover
- One phone line for London, the South East and Scotland

Quoting for work in Penge
These are the things that shape the price:
- Phasing around occupants
- Which sealant the job calls for
- Access and working height
- Quantities, in metres or numbers
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.
What to include in your enquiry
A few photos plus some basic facts will normally do. It helps to include:
- Where the site is, with the postcode
- How the joints are reached, and at what height
- A wide shot and a close-up of the area
- Rough lengths or quantities, or drawings if you have them
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
When it isn’t the sealant
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Structural cracks or movement the joints weren’t designed for
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
If you’re not sure, just give us a call on 01277 525 020 or email us and we’ll give you a straight answer before you book.
What we seal
- Washrooms and tea points
- Window and door perimeters
- External facade joints
- Movement joints in walls and floors
- Kitchen worktops and splashbacks
- Floor and threshold joints

From enquiry to sign-off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- First, details reach us through the quote form or a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Let building users know which areas are affected
- Agree which areas must stay open

Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Do you need commercial sealant contractors in Penge?
When a bead peels cleanly off one face, it has failed in adhesion. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. We see it often where joints were sealed in a hurry.
Common reasons buildings call us in:
- Expansion joints with the sealant torn out
- External beads that have gone brittle and cracked
- Shrunken sealant along kitchen worktops and splashbacks
- Untidy joints in a reception, shop floor or lobby
Occupiers with premises at both Franklin Industrial Estate and Clyde Vale Industrial Estate could have the sealant at each handled under one quote.
What to look for in a quote
- The terms of the workmanship guarantee
- How they handle RAMS and site documents
- Health and safety accreditation such as CHAS
- What level of public liability insurance do they hold?
