About our coloured sealant in Harefield
In retail, hospitality and office fit-outs, joints are seen close up every day. A mismatched bead can make good joinery look unfinished. The aim is a colour from the product’s range that disappears into the surface. We work on shop-fit joinery and counters, natural stone and brick and powder-coated and anodised frames, and what we are called in for most is colour changes after a rebrand or refit and hotel refurbishments with a set colour scheme. Whether you call it commercial sealant work, mastic application or joint sealing, in Harefield it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
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 workmanship is guaranteed for 12 months, in Harefield as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Sealant on show in Harefield’s commercial buildings
In London, commercial buildings often have managed loading bays, goods lifts and permit-to-work systems. We fit into those systems and phase the work so the building keeps operating. There are three care or nursing homes within about 2 miles of Harefield. 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.
Sites a few miles apart, such as Woodcock Hill Industrial Estate and Peerglow Industrial Estate, can share one programme and one point of contact. Harefield is inside London’s ULEZ, as is the rest of Greater London; tell us about loading bays, goods lifts and parking when you send details. Shops and cafés around stations like Denham station (2 miles south of Harefield) trade from early, so work is timed around them.
Harefield is about 3 miles south of Rickmansworth, in Greater London. Our applicators travel to Harefield for work on colour-matched joints. Harefield is one of 764 places we cover in Greater London for colour-matched joints. There’s a separate page for London, roughly 18 miles from Harefield.

Other services in Harefield
Site staff or a sealant specialist?
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.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- Repairing damaged frames or cladding
- A guaranteed perfect match to every finish
- Colour variation across natural stone or brick that no single shade can match
If you’re not sure, just speak to us on 01277 525 020 or email us and we will give you a straight answer.
Surfaces we seal
- Shop-fit joinery and counters
- Natural stone and brick
- Office fit-out finishes
- Powder-coated and anodised frames
- Cladding panels
- Hotel bathrooms and public areas
What the job involves on each surface
Powder-coated and anodised frames
Metallic and anodised finishes are hard to match exactly with sealant. We will suggest the nearest standard colours.
Shop-fit and joinery finishes
Retail fit-outs mix many finishes in a small space. Each joint gets a colour that suits the materials it sits between as agreed with the designer.
From enquiry to sign-off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. 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.
- The sealant type is chosen for the joint first, then the colour.
- Colour references, samples or photos of the finish are checked against the product’s range.
- A short trial length can be approved before the full run on visible work.
- We take out the existing bead, clean the joints and fit backing.
- We apply the agreed colour and tool it neatly, with masking where the finish needs it.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Send any specification or drawings in advance
- Flag any permit to work we will need

Questions about Harefield
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we will plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Can the sealant on our Harefield premises match the finishes?
Yes, we can usually get close to most finishes from the product’s colour range. The quote lists the colours the product is made in.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or email us. Include photos or drawings if you have them.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Owners, agents and contractors
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
