Coloured sealant for Gilbert Street sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Coloured sealant in Gilbert Street, done properly
Window, door and shopfront frames in RAL finishes often need a sealant to suit. We compare the RAL reference with the colours made for the specified sealant, and the nearest option is agreed with you. Where nothing in the range is close enough, a paintable hybrid or PU sealant may be an alternative, if the joint and specification allow. The enquiries we see most involve old colour-matched joints lifting at the edges and discoloured joints on a visible elevation, across powder-coated and anodised frames, natural stone and brick and hotel bathrooms and public areas. Facilities teams, main contractors and managing agents in Gilbert Street tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Work in smaller places such as Gilbert Street tends to come one building at a time: a pub kitchen, a hall, a small office. We will want a full list and photos first, so the right products come on the day and nothing waits for a second trip.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Maintenance after handover
Your facilities or cleaning team can help the joints last. Share these points with them:
- Settle the colour with the designer at the start
- Keep the area clear while the sealant cures
- Keep the same sealant colour across a brand
- Note which sealant colour was used where
Note the sealant type and colour on the building file. It makes matching later repairs much easier.
Make sure every contractor knows which sealant and colour are on the building file. That keeps new work in line with what’s there.
Common questions from Gilbert Street clients
Can you supply sealant in our brand colour for a site in Gilbert Street?
Yes, we can typically get close to most finishes from the product’s colour range. The quote lists the colours the product is made in.

Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Sealant on show in Gilbert Street’s commercial buildings
Less than 3 miles from Gilbert Street there are two named estates and business parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints. Rainfall across the South East, Gilbert Street included, is lower than in many parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it.
A business with units at Lower Soldridge Business Park and Mansfield Business Park needn’t use two contractors for its sealant. On a business park such as Lower Soldridge Business Park, 1.7 miles to the north of Gilbert Street, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.

Other services in Gilbert Street
Different surfaces, different methods
Powder-coated and anodised frames
Metallic and anodised finishes are hard to match exactly with sealant. We will suggest the nearest standard colours for approval.
Natural stone
Sandstone, limestone and granite each have distinct tones. We choose from the product’s range and agree the colour with you after a sample if needed.
When it isn’t the sealant
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Custom-mixed sealant colours
- Stopping sealant from ever changing colour outdoors
- Paintable products in joints they aren’t suited to
If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Leave it or put it right?
Standard white or grey sealant is cheaper to stock, but it doesn’t always suit the finish. Where joints are on show, choosing a better colour is normally worth it in how the finished space looks. Converted and older buildings near places like Gilbert Street tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
