Coloured sealant in The Hale

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What sealant work can’t fix

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Paint over sealant on joints that move too much
  • A colour that never alters with age
  • Repairing damaged frames or cladding

If you’re not sure, just phone 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

Where we work in The Hale

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

Coloured sealant in The Hale, done properly

In retail, hospitality and office fit-outs, joints are seen close up every day. A grey bead on a black shopfront or a white line against oak looks like a defect, however well it was installed. We pick a colour from the product’s range that sits with the finish. If you have poorly tooled joints on visible finishes and failed coloured sealant that has split or peeled, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in The Hale, preparation and product choice get the time they need.

For managing agents and FMs looking after premises in The Hale, access is typically the first question: loading bay slots, goods lifts, permits to work and somewhere to keep materials. With access agreed, we work through the colour-matched joints a section at a time, keeping disruption to tenants low.

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.

Aftercare for building managers

Regular inspection catches problems early. Specifically:

  • Use one colour standard across multi-site work
  • Record the product and colour reference on the building file
  • Insist on the agreed colour for any repair
  • Put the colour reference on the finishes schedule

Expect some change in appearance over the years. Some fading is part of normal ageing outdoors.

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.

When to bring in a specialist

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.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

From enquiry to sign-off

At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. First we agree which sealant type the joint needs.
  2. We compare the target colour with the colours available.
  3. The nearest colour is agreed, with a sample bead where needed.
  4. We cut out the existing bead, clean and set the depth.
  5. We mask, seal and tool to a clean line.
  6. We remove the masking and walk the finished joints with you.

Getting the site ready

  • For older buildings, check the asbestos register before work
  • Clear stock, furniture or equipment away from the joints
  • Point out parking and an unloading spot

Questions about The Hale

Do hotels near The Hale have to close for sealant work?

Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.

Do you take on jobs in The Hale where loading and access are tightly controlled?

Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

How long does a typical visit take?

That varies with the scale of the job, but the work usually takes a few hours or a phased programme, depending on joint lengths and how many colours are involved. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

For managing agents and facilities managers

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

What the job involves on each surface

Hotel interiors

Phased resealing lets rooms go back into use quickly. We plan around your occupancy with areas kept in use.

Office fit-outs

Office fit-outs include glazed partitions, kitchens, washrooms and reception areas. Colour-matched joints keep the finish consistent across floors at handover.

Commercial premises in The Hale

The 3 miles around The Hale take in at least three named trading estates, business parks or retail parks. Each new occupier on a park like these tends to refit, from reception to staff kitchen, often in a colour the occupier specifies. A number of hotels sit less than 2 miles from The Hale. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter, with rooms done in turn while the rest stay let.

For a hotel such as Railway Hotel, which lies south-west of The Hale, the colour of a joint at the bar or the bath matters to the look of the room. If you have premises on more than one site, say at Mill Hill Industrial Estate and Mill Yard Industrial Estate, one contractor and one quote can cover both. For a shop at a centre such as Broadwalk Centre, 0.8 miles south-west of The Hale, tidy joints at counters and displays matter as much as the fixtures.
