Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Keep the same sealant colour across a brand
- Keep harsh solvents away from visible joints
- Put the colour reference on the finishes schedule
- Plan full-run reseals on visible elevations
Keep a record of the product and colour reference used. It makes matching later repairs much easier, with no guesswork.
Put the sealant colour into the specification or finishes schedule. When colour is left to the last minute, it is often wrong.
About our coloured sealant in North Cray
On a finished interior or a high-quality elevation, the sealant is part of the look. We install coloured and colour-matched sealant so joints sit quietly against cladding, stone, brick, frames and shop-fit finishes. Performance decides the product; the colour is chosen from that product’s range. If you have coloured joints that have cracked with movement and marked sealant in hotel bathrooms, we can help. Searching for sealant specialists in North Cray? We have been sealing commercial buildings since 2005.
For managing agents and FMs looking after premises in North Cray, 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.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Common questions from North Cray clients
Will our hotel in North Cray need to close for the work?
Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.
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. Share the building’s contractor rules and we will work to them. All of Greater London is inside the ULEZ, and our planning allows for it
Is North Cray in your area?
Yes. Sites across North Cray are covered.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit usually takes about the same time as any other sealant work, plus a little longer if a sample bead is agreed first. For bigger or phased jobs, we’ll set out a timescale with the quote.
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 photos and a postcode.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. 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.
Working on commercial sites near North Cray
Most London commercial buildings run contractors through a reception, a permit system and booked goods-lift slots. We fit into those systems and phase the work so the building keeps operating. North Cray has several hotels close by, all within 2 miles. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet; work is planned so the hotel keeps trading.
Sites a few miles apart, such as Old Bexley Business Park and Crayfields Business Park, can share one programme and one point of contact. Access in North Cray needs thought: the ULEZ covers all of Greater London, and loading and parking are rarely simple. Units at places like Broadway Shopping Centre, 1.7 miles north of North Cray, are refitted as brands change, and the joints have to suit each new scheme.

Doing it in-house
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.
Certain joints really need a specialist: for example 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.
On site: what to expect
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a job in North Cray, access comes first. Give us the hours we can be on site and we will schedule to suit.
- The sealant type is chosen for the joint first, then the colour.
- Colour references, samples or photographs of the finish are checked against the product’s range.
- Where colour is critical, a sample bead can be agreed in a discreet spot.
- We remove the existing bead, clean the faces and set the depth.
- We apply the agreed colour and tool it neatly, with masking where the finish needs it.
Before we start on site
- For older buildings, check the asbestos register before work
- Clear stock, furniture or equipment away from the joints
- Have the specification and drawings to hand
Quotes

Advice
Why it’s worth doing now in North Cray
Resealing a full run gives a consistent colour. Small repairs at different times rarely match, so a planned reseal often looks better value. Failed sealant in a building in North Cray can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Surface by surface
Shop-fit and joinery finishes
In shops, joints are at eye level and inspected by customers. Clean masking and neat tooling matter as much as colour.
Brick and masonry
Brickwork joints normally look best in a colour close to the mortar or brick. The nearest colour in the range is agreed with you before work starts.
