Coloured sealant in Cambridge Heath

We take on colour-matched work across new fit-outs, refurbishments and resealing of existing joints on sites in Cambridge Heath. When replacing old joints, the new colour usually has to match what’s already there, particularly where the building’s look matters. We work on cladding panels, natural stone and brick and office fit-out finishes, and what we are called in for most is coloured joints that have cracked with movement and colour changes after a rebrand or refit. For commercial sealant work in Cambridge Heath, you deal with one contact from quote to sign-off, whether it’s one building or several.

Buildings in a London area such as Cambridge Heath 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.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself typically taking a day for a modest shop fit, and longer for a full building or several floors. In Cambridge Heath, 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. Photos or drawings show us the finishes and joints.
  2. Colour options from the specified product’s range are shared with you.
  3. Tell us your site hours and access windows and we’ll plan around them.
  4. We prepare each joint, prime where needed and fit backing.
  5. We seal in the approved colour and tool it smooth.

Preparing the site

  • Send your site hours and access windows
  • Send any specification or drawings in advance
  • Let building users know which areas are affected

Advice

Sealant on show in Cambridge Heath’s commercial buildings

Cambridge Heath has at least three named business or industrial parks inside a 3-mile radius. Each new occupier on a park like these tends to refit, from reception to staff kitchen; brand colours often come into it. Cambridge Heath 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; work is planned so the hotel keeps trading.

In hotels such as Town Hall Hotel & Apartments (under half a mile south of Cambridge Heath), refurbishments normally mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. For premises near Cambridge Heath station, which lies south of Cambridge Heath, footfall is part of the plan: work is phased so shops and offices keep trading.

Cambridge Heath is about 1 mile north-east of Shoreditch, in Greater London.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Record the product and colour reference on the building file
  • Reseal whole runs rather than patching single joints
  • Protect fresh coloured sealant from dust and handling
  • Don’t let trades patch coloured joints with a random sealant

Don’t let anyone patch a coloured joint with whatever sealant is to hand. Wrong-colour patches are obvious, undoing the look you paid for.

Approve a sample where colour really matters. Seeing the cured colour in place avoids surprises.

What we can’t put right

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Materials with mixed tones that defy a single match
  • Paintable products in joints they aren’t suited to
  • Restoring stained stone or masonry next to old sealant

Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we will tell you honestly.

When to call us in Cambridge Heath

Most enquiries start with a joint that looks wrong: a pale bead on a dark frame, or an old seal that has discoloured. A better-matched colour fixes the appearance without changing the joint’s job.

It’s worth sending us details if you spot any of the following:

  • Marked sealant in hotel bathrooms
  • A run of joints in mismatched shades
  • Old colour-matched joints lifting at the edges
  • Joints that need to match a new RAL frame colour

Occupiers with premises at both Bayford Street Industrial Centre and Anchor Retail Park could have the sealant at each handled under one quote.

Questions to ask before you book

  • How they’ll work around occupants
  • Do they follow the manufacturer’s priming guidance?
  • The terms of the workmanship guarantee
  • How joint depth will be controlled

How to choose a sealant contractor

Should maintenance staff do it?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Surface by surface

Brick and masonry

Brickwork joints typically look best in a colour close to the mortar or brick. We choose a suitable shade from the product’s range.

Paintable sealants

Overpainting is most common on internal joints with little movement. If the joint needs a product that can’t be painted, we say so.

Common questions from Cambridge Heath clients

Do you work in London buildings with loading restrictions?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. The ULEZ covers the whole of Greater London, which we allow for

Is Bayford Street Industrial Centre, near Cambridge Heath, within your area?

Yes. Our area takes in Cambridge Heath and its surroundings, with estates and business parks such as Bayford Street Industrial Centre included. Photos and a short description are enough for a first look.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Can staff carry on working while you’re here?

Typically, yes. We phase the work so most of the building stays in use, with each area protected and signed.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Can wet areas have colour-matched sealant?

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

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
