Common questions from North Cheam clients

Does a hotel in North Cheam need to shut while its sealant is renewed?

In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.

Can you cope with the access rules in a London building?

Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it

Do you match sealant to RAL colours?

Yes. RAL references are a common way to specify sealant colour. We’ll confirm the colours available for the specified product.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Can you match any colour exactly?

No. An exact bespoke match isn’t something we can promise. We will show you the closest colours in the specified product’s range for your approval.

How do I request a quote?

Coloured sealant in North Cheam, done properly

A colour-matched bead still has to work as a seal. Each joint is cleaned, backed to depth and tooled firmly onto both faces. Clean masking and steady tooling give the sharp lines colour work needs. Most enquiries involve discoloured joints on a visible elevation and fit-outs with a sealant colour in the specification, on natural stone and brick, cladding panels and powder-coated and anodised frames. Most enquiries from North Cheam start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Much of the planning for a London commercial job is about getting in and out: loading bay slots, goods lifts, permits to work and somewhere to keep materials. Once that’s settled, the colour-matched joints are resealed in sections so tenants are disturbed as little as possible.

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.

Doing it in-house

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Putting right a botched joint often costs more than sealing it well at the start, 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.

Cost factors for colour-matched joints

We price every job individually. The main factors are:

  • Any access equipment needed
  • Working within restricted access windows
  • Site requirements such as inductions and permits
  • Quantities, in metres or numbers

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Before you send an enquiry

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • Access details, including height
  • The type of building and who uses it
  • Specification clauses that apply
  • A wide shot and a close-up of the area

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Looking after the joints

To get the most from the new sealant:

  • Check a trial length in real light
  • Insist on the agreed colour for any repair
  • Use one colour standard across multi-site work
  • Settle the colour with the designer at the start

Don’t let anyone patch a coloured joint with whatever sealant is to hand. A mismatched repair stands out, undoing the look you paid for.

Make sure every contractor knows which sealant and colour are on the building file. It stops mismatched repairs creeping in.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  1. We confirm the joint type and the product it 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. 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

  • Point out any areas we must not close
  • Warn occupants and staff about the work
  • For older buildings, check the asbestos register before work

Why it’s worth doing now in North Cheam

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

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

What North Cheam’s businesses ask us to seal

The 3 miles around North Cheam take in at least three named trading estates, business parks or retail parks. Sites like these see regular refits, with shopfronts, offices and staff areas to seal. Most London commercial buildings run contractors through a reception, a permit system and booked goods-lift slots. We plan around them and agree phasing so tenants and customers aren’t disrupted.

If you run a unit on an estate such as Kimpton Industrial Park, 0.6 miles to the north-east of North Cheam, the trade counter, offices and staff facilities have joints to look after as well as the warehouse. Offices and shops close to stations such as West Sutton station, 0.8 miles to the south-east of North Cheam, tend to be busy all day, so sealant work is planned around opening hours. In hotels such as Nonsuch Park Hotel, which lies south-west of North Cheam, refurbishments normally mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.
