About our coloured sealant in Clerkenwell
Stone, brick and cladding each bring their own colour challenge: a stone or brick facade shifts in tone from one area to the next. We choose a colour that reads well across the surface rather than chasing one spot, agreed on site where needed. We work on cladding panels, hotel bathrooms and public areas and powder-coated and anodised frames, and the failures we’re asked to look at most are failed coloured sealant that has split or peeled and smeared sealant on stone or joinery. Looking for mastic applicators who cover Clerkenwell? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
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. With access agreed, we work through the colour-matched joints a section at a time, keeping disruption to tenants low.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

How the quote is worked out
We price every job individually. The things that drive the figure:
- Location, for remote and island sites
- How much existing material needs removing
- The size and state of each joint
- How much there is to seal
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
What we need to price the job
For an accurate fixed quote, we need to understand the site. Send us:
- Any specification or named product
- Approximate linear metres or a joint schedule
- The type of building and who uses it
- The site address and postcode
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or give us a call on 01277 525 020 or email a schedule or drawings to discuss it first.
Shops, offices and hotels in and around Clerkenwell
Clerkenwell has two care or nursing homes no more than 2 miles away. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound, often in colours that suit the décor. Less than 3 miles from Clerkenwell there are at least three named estates and business parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal, often in a colour the occupier specifies.
Units at places like Brunswick Centre (to the west of Clerkenwell) are refitted as brands change, and the joints have to suit each new scheme. Trade counters and showrooms on estates such as Roman Way Industrial Estate (to the north of Clerkenwell) need neat joints where customers see them.
Clerkenwell is about 2 miles north of London, in Greater London. Across the N1 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Clerkenwell is one of 764 places we cover in Greater London.

Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Avoid abrasive pads on coloured sealant
- Settle the colour with the designer at the start
- Insist on the agreed colour for any repair
- Avoid piecemeal repairs on coloured joints
Clean coloured joints with mild, non-abrasive products. Harsh chemicals and scouring can change how the colour looks.
Settle the colour early in the project. When colour is left to the last minute, it is often wrong; fixing it early prevents rework.
How a job runs
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We confirm the joint type and the product it needs.
- Your RAL reference, sample or photo is checked against that product’s colours.
- You approve the colour, on site if it’s critical.
- We cut out the existing bead, clean and set the depth.
- Edges are masked and the coloured sealant applied and tooled.
- We remove the masking and walk the finished joints with you.
What we need from you
- Point out parking and an unloading spot
- Have the specification and drawings to hand
- Let us know about inductions and permits

FAQs: Clerkenwell
Will our hotel in Clerkenwell need to close for the work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.
Does your area include sites such as Roman Way Industrial Estate, near Clerkenwell?
Yes. We cover Clerkenwell and the area around it, including industrial estates, business parks and retail parks such as Roman Way Industrial Estate. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.
Do you match sealant to RAL colours?
Yes. Give us the RAL reference and we’ll check it against the product’s range. You’ll see the nearest options at quote stage.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Does the colour affect how the joint performs?
Performance comes from the sealant type and the installation. We choose the right product for the joint first and then pick from its colour range, installed in exactly the same way.
Can coloured sealant be used in washrooms and kitchens?
Yes, where the product range allows. Hotel bathrooms, washrooms and kitchens often use coloured sanitary silicone to suit tiles or stone in commercial interiors.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Do you need coloured sealant in Clerkenwell?
Joints repaired piecemeal often end up in several shades. Mixed repairs over time leave a run of mismatched joints. Resealing a whole run in one agreed colour tidies it up.
Common reasons buildings call us in:
- Smeared sealant on stone or joinery
- Shop fits that need consistent sealant colours across sites
- Sealant that no longer suits recoated frames
- Marked sealant in hotel bathrooms
For premises near Farringdon station, less than half a mile south of Clerkenwell, footfall is part of the plan: work is phased so shops and offices keep trading.
What your quote should include
- Their approach to joint depth and backing

Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
