What the job involves on each surface

Cladding panels

Where panels vary in colour, the joint colour is agreed for the whole elevation. Sometimes a mid-tone suits better than matching one panel and we can trial it first.

Paintable sealants

Overpainting is most common on internal joints with little movement. We will tell you if a joint needs a non-paintable product.

How we handle coloured sealant in Aldwych

Coloured sealant is a finishing trade, so it typically comes late in a programme. We work around other trades and protect adjacent finishes. Our workmanship carries a 12-month guarantee. We work on shop-fit joinery and counters, natural stone and brick and powder-coated and anodised frames, and the usual reasons a site gets in touch are discoloured joints on a visible elevation and marked sealant in hotel bathrooms. Looking for mastic applicators who cover Aldwych? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

For managing agents and FMs looking after premises in Aldwych, access is usually the first question: booked loading, goods-lift times, the permit system and a place to stage materials. With access agreed, we work through the colour-matched joints a section at a time, keeping disruption to tenants low.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

When to bring in a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes about the same time as any other sealant work, plus a little longer if a sample bead is agreed first, and our waste is bagged and taken away as we go. All of Greater London is in the ULEZ, and kerbside space in Aldwych can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. Photos or drawings show us the finishes and joints.
  2. We send the closest colours from the product’s range.
  3. The programme and access are agreed, including any phasing.
  4. We prepare each joint, prime where needed and fit backing.
  5. The agreed colour is installed and tooled neatly.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Confirm the product named in the specification
  • Explain the parking and delivery arrangements

What Aldwych’s businesses ask us to seal

The 3 miles around Aldwych 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, often in a colour the occupier specifies. A good number of hotels sit less than 2 miles from Aldwych. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme, and the work can be phased so the rest of the hotel keeps trading.

Industrial estates such as Grand Vitesse Industrial Estate (0.9 miles south-east of Aldwych) have offices, trade counters and welfare areas whose sealant ages like any other building’s. A hotel such as Hotel Strand Continental (under half a mile south of Aldwych) shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

Quoting for work in Aldwych

We price every job individually. The things that drive the figure:

  • How much existing material needs removing
  • Whether the work must be split into stages
  • The size and state of each joint
  • The site’s rules and procedures

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Before you send an enquiry

However big the job, the same details help:

  • Clear photos of the problem areas
  • The type of building and who uses it
  • Access details, including height
  • The postcode of the building

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or email the details over.

FAQs: Aldwych

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

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

Will our hotel in Aldwych need to close for the work?

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

Can we specify the colour by RAL number?

Yes. Many specifications give the sealant colour as a RAL number. We’ll confirm the colours available for the specified product.

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

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

What happens if it’s left?

People notice sealant lines more than you might expect, particularly on high-end finishes. Resealing in a suitable colour is a modest cost against the finishes it sits beside, and it lifts the whole area. Getting scaffold, permits or access booked in Aldwych takes effort, so it makes sense to deal with every failing joint while access is in place.

The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Why choose Mastic Doctor in Aldwych

  • Clear, fixed quotes
  • Matching to RAL references, product permitting
  • Joints cleaned back to sound surfaces
  • Work carried out by CSCS-carded applicators

See our cost guide or how we’re accredited.

Do you need coloured sealant in Aldwych?

Exposure takes its toll on colour. UV, grime and weathering alter how a bead looks after a few years. Resealing is the chance to reset the colour.

Site and facilities staff are often the first to spot these:

  • Shop fits that need consistent sealant colours across sites
  • White or grey sealant that clashes with the finish
  • Old sealant that has yellowed, darkened or faded
  • Smeared sealant on stone or joinery

For a shop at a centre such as Brunswick Centre (0.8 miles north of Aldwych), tidy joints at counters and displays matter as much as the fixtures.
