What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Quantities, in metres or numbers
  • Joint width, depth and condition
  • Distance, for remote addresses
  • How much existing material needs removing

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

Before you send an enquiry

However big the job, the same details help:

  • Approximate linear metres or a joint schedule
  • Asbestos survey details if the building is older
  • Access details, including height
  • Photos of the joints, close up and from further back

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

About our coloured sealant in Middle Park

A coloured bead has to perform like any other sealant. Each joint is cleaned, backed to depth and tooled firmly onto both faces, with no shortcuts because it’s decorative. Careful masking keeps the edges crisp. If you are dealing with joints that need to match a new RAL frame colour and standard-colour sealant spoiling a high-end finish, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Middle Park, that means joint design, primers and backing rod as standard.

London’s commercial stock mixes period buildings turned into offices with modern glass and steel, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.

A 12-month guarantee applies to all our work in Greater London. If an installation problem shows up, ring 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

How the job changes by surface

Office fit-outs

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

Powder-coated and anodised frames

Window, door and shopfront frames in RAL colours often need a sealant to suit. The frame colour is checked against what the product is made in, and you confirm the choice.

Diagnose, treat, sign off

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. In Middle 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 confirm the joint type and the product it needs.
  2. We compare the target colour with the colours available.
  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. Edges are masked and the coloured sealant applied and tooled.
  6. Masking comes off and the work is checked with you.

Getting the site ready

  • Confirm the product named in the specification
  • Tell staff and tenants when we’ll be in
  • Let us know about inductions and permits

FAQs: Middle Park

Do hotels near Middle Park have to close for sealant work?

Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.

Can you work in a London building with booked loading and goods-lift slots?

Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Is any job too small?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

What’s the quickest route to a quote?

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

Can coloured sealant be used in washrooms and kitchens?

Yes. Sanitary silicones with anti-mould additives come in a range of colours too. We will confirm what’s available for the specified product.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Custom-mixed sealant colours
  • Materials with mixed tones that defy a single match
  • Preventing all fading from sunlight and weathering

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

Surfaces we seal

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

Building owners, agents and FMs in Middle Park

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.

What Middle Park’s businesses ask us to seal

There are a number of hotels within about 2 miles of Middle Park. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme. Middle Park has six care or nursing homes no more than 2 miles away. Care homes need tidy, cleanable joints in kitchens, corridors and communal rooms; colours can be chosen to suit the interior.

In a retail centre such as Lewisham Shopping Centre, which lies north-west of Middle Park, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish. For tenants and agents on sites such as Green Lane Business Park, which lies south-east of Middle Park, office fit-outs, reception joints and window perimeters are the usual sealant work. A business with units at Green Lane Business Park and Chiltonian Industrial Estate needn’t use two contractors for its sealant.

Middle Park is about 1 mile west of Eltham, in Greater London. We send applicators to Middle Park for colour-matched joints. We work across 764 places in Greater London. Sites around London have their own page, about 7 miles away.

For a building on Horsa Road, Court Road and Sidcup Road or nearby, we can quote for colour-matched joints.

Should maintenance staff do it?

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

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
