Coloured sealant for businesses in Northumberland Park

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Why act early in Northumberland Park

Across a chain of shops or hotels, consistency matters. Fixing the colour reference at the start keeps every site the same across the programme. Getting scaffold, permits or access booked in Northumberland Park takes effort, so it makes sense to deal with every failing joint while access is in place.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Why clients in Northumberland Park choose us

  • CSCS-carded applicators
  • Sealing commercial buildings since 2005
  • 12-month guarantee on workmanship
  • Colours confirmed for the specified product

Coloured sealant for commercial buildings in Northumberland Park

Where colour is critical, a sample bead in a discreet spot settles the question. Sealant can look slightly different once it has cured, and again in different light, so approving a sample on site is worth doing. Let us know who signs off colour, and we will fit the sample into the programme. If you are dealing with joints that need to match a new RAL frame colour and smeared sealant on stone or joinery, we can put it right, on shop-fit joinery and counters, natural stone and brick and cladding panels alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Northumberland Park, that means joint design, primers and backing rod as standard.

Buildings in a London area such as Northumberland Park 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, and where a brand finish matters, the sealant colour is agreed first.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Questions about Northumberland Park

Is Compass West Industrial Estate, near Northumberland Park, within your area?

Yes, sites like Compass West Industrial Estate are within our area, along with the rest of Northumberland Park. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Will our hotel in Northumberland Park 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.

Can staff carry on working while you are here?

In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Are you CHAS accredited?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

How much does the work cost?

Each job is quoted on its own details. For yours, phone 01277 525 020 or email the details over with a description of the work.

Does the colour affect how the joint performs?

Colour is a choice within a product’s range, not a separate type of sealant. Preparation, backing and tooling are what make it last in any colour.

Will sunlight affect the sealant colour?

Some change is normal outdoors. UV and grime can soften or alter the colour, and resealing brings the look back.

On site: what to expect

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. 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.

  1. First we agree which sealant type the joint needs.
  2. We compare the target colour with the colours available.
  3. You approve the colour, on site if it’s critical.
  4. We cut out the existing bead, clean and set the depth.
  5. Edges are masked and the coloured sealant applied and tooled.
  6. We remove the masking and walk the finished joints with you.

What we need from you

  • Have the specification and drawings to hand
  • Tell staff and tenants when we’ll be in
  • Send your site hours and access windows

How the job changes by surface

Natural stone

Stone has variation, so the aim is a colour that sits naturally against it. A stone-compatible, neutral-cure sealant avoids staining.

Office fit-outs

Partition frames and joinery are often in a set colour. We match from the product’s range.

What sets the cost

To price the job, we consider:

  • Which sealant the job calls for
  • Any access equipment needed
  • Site requirements such as inductions and permits
  • Location, for remote and island sites

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • Access details, including height
  • Any specification or named product
  • Clear photos of the problem areas
  • Any dates the work must fit around

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Owners, agents and contractors

We work for building owners and managing agents on everything from one building to a spread of sites around Northumberland Park. One quote can cover more than one site, which keeps the paperwork simple.

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 will confirm with the quote.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Colour variation across natural stone or brick that no single shade can match
  • Paint over sealant on joints that move too much
  • A colour that never alters with age

If in doubt, call the office on 01277 525 020 or email us and we will say what we think.

What we seal

  • Powder-coated and anodised frames
  • Hotel bathrooms and public areas
  • Natural stone and brick
  • Cladding panels
  • Office fit-out finishes
  • Shop-fit joinery and counters

Frontages, fit-outs and joints in Northumberland Park

Northumberland Park has three 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. The 3 miles around Northumberland Park take in at least three named trading estates, business parks or retail parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal.

A unit on an estate like Compass West Industrial Estate, under half a mile north of Northumberland Park, normally has an office front, a trade counter and staff facilities with joints of their own. If you have premises on more than one site, say at Compass West Industrial Estate and Tottenham Commercial Park, one contractor and one quote can cover both. Units at places like Ravenside Retail Park, 0.8 miles to the north-east of Northumberland Park, are refitted as brands change, and the joints have to suit each new scheme.
