Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Keep the same sealant colour across a brand
- Avoid abrasive pads on coloured sealant
- Brief cleaners about newly sealed joints
- Approve a sample bead on high-profile areas
Give the sealant its full cure time before cleaning or handling the area. Coloured sealant marks more visibly than white while it is fresh.
Settle the colour early in the project. When colour is left to the last minute, it is often wrong, so agree it with the designer at the start.
Coloured sealant for commercial buildings in Northaw
Coloured sealant work ranges from a new shop fit to replacing failed joints on an existing building. When replacing old joints, the new colour usually has to match what’s already there. If you are dealing with previous reseals that don’t match the original and white or grey sealant that clashes with the finish, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Northaw, preparation and product choice get the time they need.
Rural business units near smaller places such as Northaw are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What we can’t put right
Being straight saves everyone time. New sealant won’t cure:
- Stopping sealant from ever changing colour outdoors
- Materials with mixed tones that defy a single match

Northaw: questions and answers
Is a smaller place like Northaw outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can the sealant on our Northaw premises match the finishes?
Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Available colours for the product are confirmed with the quote.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited and a Constructionline member.
On site: what to expect
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a few hours or a phased programme, depending on joint lengths and how many colours are involved, and our waste is bagged and taken away as we go. If others near Northaw need work, visits can be combined. A fixed quote is given before anything starts.
- The sealant type is chosen for the joint first, then the colour.
- We compare your RAL reference or sample with the colours made for that sealant.
- A short trial length can be approved before the full run on visible work.
- 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.
What we need from you
- Tell us your opening times and when work is allowed
- Have the specification and drawings to hand
- Tell staff and tenants when we’ll be in

Common problems we fix in Northaw
Most enquiries start with a joint that looks wrong: a pale bead on a dark frame, or an old seal that has discoloured. A better-matched colour fixes the appearance without changing the joint’s job.
These are often picked up first by site or facilities staff:
- Discoloured joints on a visible elevation
- Sealant that no longer suits recoated frames
- Stained or mouldy coloured joints in washrooms
- Standard-colour sealant spoiling a high-end finish
Sites a few miles apart, such as Hollies Way Industrial Park and Sopers Road Industrial Estate, can share one programme and one point of contact.
What your quote should include
- Is the sealant right for the movement and the substrate?
- Will failed sealant be removed rather than covered?
- Do they follow the manufacturer’s priming guidance?
- How they handle RAMS and site documents

Commercial premises in Northaw
Northaw has at least three named business or industrial parks inside a 3-mile radius. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints; brand colours often come into it. Northaw sits in one of the drier corners of the country, the South East. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.

How the job changes by surface
Paintable sealants
Some joints are better sealed with a paintable product and decorated. It depends on movement and the specification because paint may crack where the joint moves.
Natural stone
Natural stone rarely has one colour, and the sealant has to work with that. A stone-compatible, neutral-cure sealant avoids staining.
