How we handle commercial sealant contractors in Adelphi
We’ve applied sealant on commercial sites for over 20 years: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. If your site needs RAMS, an insurance certificate or CSCS details, say so and we’ll confirm with the quote. Site teams most often ask us about external beads that have gone brittle and cracked and messy, uneven beads from earlier work that let the building down, on movement joints in walls and floors, kitchen worktops and splashbacks and external facade joints. Facilities teams, main contractors and managing agents in Adelphi tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
A lot of what we do in Adelphi is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
In London, most commercial sealant work happens in buildings that stay open: offices with staff at their desks, shops trading below flats and receptions that can’t be roped off for long. Work is split into zones agreed with the building or facilities manager, so the premises keep working around us.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Building owners, agents and FMs in Adelphi
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
What sets the cost
Each job is priced on its own details. The main factors are:
- Which sealant the job calls for
- Location, for remote and island sites
- Any access equipment needed
- Removal of failed or old sealant
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What to include in your enquiry
For an accurate fixed quote, we need to understand the site. Send us:
- When you need the work done
- The asbestos register, for older buildings
- The postcode of the building
- Rough lengths or quantities, or drawings if you have them
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
Why it’s worth doing now in Adelphi
Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. In many cases the element is fine and only the seal around it has given up. Resealing typically costs far less than renewal. Getting scaffold, permits or access booked in Adelphi takes effort, so it makes sense to deal with every failing joint while access is in place.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What you get with us
- Products installed to the manufacturer’s instructions
- Joints cleaned back to sound surfaces
- Fixed quotes based on photos, drawings or a visit
- A Constructionline member, so easy to vet

What Adelphi’s businesses ask us to seal
London premises normally come with a building manager, booked loading and house rules for contractors. We fit into those systems and phase the work so the building keeps operating. At least three named trading, business or retail sites lie within about 3 miles of Adelphi. Sites like these see regular refits, with shopfronts, offices and staff areas to seal; brand colours often come into it.
Sites a few miles apart, such as Grand Vitesse Industrial Estate and Southwark Bridge Business Centre, can share one programme and one point of contact. If you run a unit on an estate such as Grand Vitesse Industrial Estate, which lies east of Adelphi, the trade counter, offices and staff facilities have joints to look after as well as the warehouse. Units at places like Brunswick Centre, 1 mile to the north of Adelphi, are refitted as brands change, and the joints have to suit each new scheme.
Adelphi is about 1 mile south-east of Marylebone, in Greater London. We cover Adelphi and the rest of Greater London, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Adelphi is one of 764 places in Greater London on our list.

What else we do in Adelphi
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Redoing a failed joint normally costs more than getting it right at the outset, 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.
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Deal with small splits before they become leaks
- On pre-2000 buildings, share the asbestos information before work starts
- Have extract fans checked so wet areas dry out
- Log reseals in the O&M or maintenance records
In washrooms and kitchens, extraction makes a real difference to sealant life. Extraction that isn’t working keeps the joints wet, which is how mould gets back in. Your maintenance team can look at extract fans at the same time.
Each spell of wet weather pushes more water through an open joint. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Resealing early keeps the problem in the sealant and out of the building.
Your questions answered
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. The building manager’s rules go straight into our method.
Does a hotel in Adelphi need to shut while its sealant is renewed?
In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
Will the building have to shut during the work?
It’s normal for us to work in occupied buildings. Only the area being sealed is closed, and the sequence is agreed in advance.
Is Adelphi in your area?
Yes. Adelphi is in our area. For a quote, call the office on 01277 525 020 or email the details over.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Which site documents can you send us?
We confirm documents at quote stage: RAMS, an insurance certificate and CSCS details are the usual requests. Every applicator holds a CSCS card.
How a job runs
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First, details reach us through the quote form or a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Where parts of the building must stay open, the work is phased.
- Old sealant is cut out completely, never sealed over.
- A suitable product for each joint goes in at the right depth and is tooled.
- A final walk-round, then the 12-month guarantee applies.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Explain the parking and delivery arrangements
- Agree which areas must stay open
