Commercial sealant contractors across Bowes Park

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What happens if it’s left?

Spot repairs have their place. If the rest of the bead is the same age and product, though, it’s usually close behind. We can price both options so you can decide on the facts. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Why us?

  • Health and safety: CHAS accredited
  • Fixed quotes based on photographs, drawings or a visit
  • One number for every site we cover
  • Workmanship guaranteed for 12 months

Commercial sealant contractors in Bowes Park

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. Before anything is cut out, we ask for the asbestos register or survey. If a material is suspected, work stops until it’s tested, and we don’t remove asbestos-containing materials ourselves. We work on washrooms and tea points, kitchen worktops and splashbacks and window and door perimeters, and what we are called in for most is earlier reseals applied straight onto the failed bead and sanitary sealant that has gone black and patchy. For commercial sealant work in Bowes Park, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Occupied buildings in Bowes Park need the work phased: we agree the order with you and hand back each area with its cure time.

Buildings in a London area such as Bowes Park rarely close for maintenance: offices with staff at their desks, shops trading below flats and receptions that can’t be roped off for long. We plan the joints floor by floor or unit by unit with the building manager, so areas stay in use, and where a brand finish matters, the sealant colour is agreed first.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

General trades versus a specialist

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Make sure ventilation in wet areas is switched on and working
  • Keep a record of which joints were resealed and when
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Deal with small splits before they become leaks

We stand behind the workmanship with a 12-month guarantee. File the handover note with the building records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.

Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. At that point it’s a repair job rather than a reseal.

For managing agents and facilities managers

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

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. We can agree access arrangements and keyholder contacts beforehand.

Shops, offices and hotels in and around Bowes Park

Bowes Park has a good number of hotels close by, all within 2 miles. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme. In London, commercial buildings often have managed loading bays, goods lifts and permit-to-work systems. Our planning starts from those rules rather than working round them later.

Shops and cafés around stations like Alexandra Palace station, less than half a mile to the south-west of Bowes Park, trade from early, so work is timed around them. In hotels such as White Lodge Hotel (1.1 miles south of Bowes Park), refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. On estates like St. George's Industrial Estate, 0.8 miles north-east of Bowes Park, the office and welfare end of each unit has its own sealant to maintain.

Bowes Park is about 3 miles south-west of Edmonton, in Greater London. We cover commercial sites throughout Bowes Park, whether it’s a single job or part of a planned programme.

From enquiry to sign-off

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes anything from part of a day on a short run of joints to several weeks on a large phased package. In Bowes Park, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. We start with the evidence: photos, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

Bowes Park: questions and answers

Will our hotel in Bowes Park need to close for the work?

Almost never. The work is phased so most rooms stay available. We agree the order of rooms and the timings with you before we start.

Do you take on jobs in Bowes Park where loading and access are tightly controlled?

Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

Do you work in Bowes Park?

Yes. We cover Bowes Park, and the simplest way to start is to give us a call on 01277 525 020 or email the details over.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Quoting for work in Bowes Park

Your fixed quote is built from the real scope. It takes account of:

  • Travel to remote or island sites
  • Joint width, depth and condition
  • Whether the work must be split into stages
  • Whether old sealant has to be cut out first

Pricing sealant joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

What we need to price the job

A few photographs plus some basic facts will normally do. Please tell us:

  • Clear photos of the problem areas
  • Drawings or a marked-up plan, if available
  • What the building is and how it’s used
  • Any specification or named product

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
