Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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.
Sealant specialists in Upper Holloway
Sometimes a split bead is a symptom rather than the cause. Water at a window perimeter might be coming from the frame, the cill or the wall behind, and repeated splits in a movement joint can mean the joint is too narrow for the movement. We look before we quote and tell you plainly if sealant won’t solve it, so budgets go where they’ll do some good. We work on movement joints in walls and floors, window and door perimeters and external facade joints, and the usual reasons a site gets in touch are sanitary sealant that has gone black and patchy and frame sealant that has cracked, shrunk or pulled away. Looking for mastic applicators who cover Upper Holloway? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
In Upper Holloway, as anywhere, the first joints to go are usually the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.
For managing agents and FMs looking after premises in Upper Holloway, access is normally the first question: booked loading, goods-lift times, the permit system and a place to stage materials. With access agreed, we work through the sealant joints a section at a time, keeping disruption to tenants low.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Do you need commercial sealant contractors in Upper Holloway?
In wet areas the enemy is usually mould rather than movement. Damp, harsh cleaning products and poor ventilation let mould take hold inside the bead. Replacement with a sanitary anti-mould silicone is the lasting answer.
Most enquiries start with one or more of the following:
- Messy, uneven beads from earlier work that let the building down
- Shrunken sealant along kitchen worktops and splashbacks
- Leaks that seem to come through a sealant line
- Window and door perimeter joints that have cracked open
Refits at hotels like St George Hotel (0.6 miles north-east of Upper Holloway) bring joints at vanity tops, bars and reception desks that guests see every day.
Questions to ask before you book
- Whether their applicators hold CSCS cards
- What site paperwork they can supply
- How the existing material will be dealt with
- Health and safety accreditation such as CHAS
What happens if it’s left?
Fixing joints complaint by complaint is a costly way to manage sealant. A planned programme groups work by building or area, cuts repeat visits and gives you a budget figure. We will suggest an order, worst sealant joints first. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

Working on commercial sites near Upper Holloway
Most London commercial buildings run contractors through a reception, a permit system and booked goods-lift slots. Our planning starts from those rules rather than working round them later. Upper Holloway has five care or nursing homes no more than 2 miles away. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound.
Industrial estates such as Bush Industrial Estate, under half a mile south of Upper Holloway, have offices, trade counters and welfare areas whose sealant ages like any other building’s. In a retail centre such as Arena Shopping Park (1.8 miles north-east of Upper Holloway), new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish.

Upper Holloway: questions and answers
Will our hotel in Upper Holloway need to close for the work?
Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.
Does your area include sites such as Bush Industrial Estate, near Upper Holloway?
Yes. Our area takes in Upper Holloway and its surroundings, with estates and business parks such as Bush Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
How do you keep disruption to occupiers down?
Phased work can be planned so areas stay in use. Tell us your site hours and access windows and we’ll plan around them.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Do you work directly for building managers?
Yes. You can send details through our quote form, and we’ll confirm any paperwork you need with the quote.

Shop fronts and retail fit-outs
Shop fits put sealant right in front of customers. Counters, display units, shopfront frames and floor trims all need a neat line, frequently colour-matched to the fit-out. Colour options are confirmed with the quote.
Window and door perimeters
Where frames meet the surrounding wall, sealant is the weather line. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.
Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes anything from part of a day on a short run of joints to several weeks on a large phased package, and our waste is bagged and taken away as we go. 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.
- Site photos, drawings or a visit tell us what’s there and how it has failed.
- You get a fixed quote covering removal, preparation and the new sealant.
- We agree the order of work, access windows and site hours with you.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- Completed areas are signed off with you under our 12-month guarantee.
Before we start on site
- Point out parking and an unloading spot
- Let building users know which areas are affected
- Make sure the joints can be reached
