Coloured sealant in Pinner Green

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

After the work

A few simple habits keep the new joints working:

  • Brief cleaners about newly sealed joints
  • Standardise colours across a portfolio
  • Put the colour reference on the finishes schedule
  • Keep the colour details for future repairs

Note the sealant type and colour on the building file. It makes matching later repairs much easier.

Put the sealant colour into the specification or finishes schedule. When colour is left to the last minute, it is often wrong; fixing it early prevents rework.

How we handle coloured sealant in Pinner Green

A colour-matched bead still has to work as a seal. Faces are prepared, depth is fixed with rod and the bead is tooled onto two sides only, with no shortcuts because it’s decorative. Clean masking and steady tooling give the sharp lines colour work needs. If you are dealing with patch repairs in several different colours and sealant that no longer suits recoated frames, we can put it right, on natural stone and brick, shop-fit joinery and counters and cladding panels alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Pinner Green it comes down to the same thing: the right product in a properly prepared joint.

Buildings in a London area such as Pinner Green 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.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email drawings and photos and we’ll come back to it.

Questions about Pinner Green

Do you work in London buildings with loading restrictions?

Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

Can you supply sealant in our brand colour for a site in Pinner Green?

Yes, we can normally get close to most finishes from the product’s colour range. Available colours for the product are confirmed with the quote.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

What will the job cost?

There isn’t a price list, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

How do I request a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

Can weather delay the job?

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.

What happens if it’s left?

It’s far cheaper to approve a sample than to strip and redo a full run. A sample takes little time compared with replacing joints in the wrong colour. Failed sealant in a building in Pinner Green can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Why us?

  • Fixed quotes based on photographs, drawings or a visit
  • Work to your specification and the manufacturer’s guidance
  • Constructionline member for supplier checks
  • Old sealant cut out, never sealed over

When it isn’t the sealant

Honesty saves time and money. New sealant won’t cure:

  • Paintable products in joints they aren’t suited to
  • Colour variation across natural stone or brick that no single shade can match
  • Stopping sealant from ever changing colour outdoors

If in doubt, speak to us on 01277 525 020 or send photos by email and we’ll say what we think before you book.

What we seal

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

How the job changes by surface

Hotel interiors

Hotels use colour-matched sealant in bathrooms, bedrooms and public areas. Sanitary silicone comes in colours too.

Powder-coated and anodised frames

Metallic and anodised finishes are hard to match exactly with sealant. We show you the closest options in the product’s range.

Shops, offices and hotels in and around Pinner Green

At least three named trading, business or retail sites lie within about 3 miles of Pinner Green. Sites like these see regular refits, with shopfronts, offices and staff areas to seal; brand colours often come into it. London premises usually 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.

Industrial estates such as Waverley Industrial Park (to the east of Pinner Green) have offices, trade counters and welfare areas whose sealant ages like any other building’s. If you have premises on more than one site, say at Waverley Industrial Park and Harrovian Business Village, one contractor and one quote can cover both. Offices and shops close to stations such as Hatch End station, 1.3 miles north-east of Pinner Green, tend to be busy all day, so sealant work is planned around opening hours.

Building owners, agents and FMs in Pinner Green

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Pinner Green. One quote can cover more than one site, which keeps the paperwork simple.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Pinner Green can sit alongside others in a wider programme.

From enquiry to sign-off

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes a day for a modest shop fit, and longer for a full building or several floors. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. First we agree which sealant type the joint needs.
  2. Your RAL reference, sample or photo is checked against that product’s colours.
  3. The nearest colour is agreed, with a sample bead where needed.
  4. The existing bead comes out, then faces are cleaned and backed.
  5. We mask, seal and tool to a clean line.
  6. Masking comes off and the work is checked with you.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Send asbestos survey details if the building is pre-2000
  • Confirm the product named in the specification
