Doing it in-house
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

What else we do in Colney Street
Common problems we fix in Colney Street
New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone.
Common reasons buildings call us in:
- Perimeter sealant that has split or peeled away
- Old perimeter mastic that has dried out
- Gaps between rainscreen or cladding panels
- Staining on stone next to old sealant
On a healthcare site such as Kingsley Green Hospital, 0.9 miles south-east of Colney Street, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Questions to ask before you book
- Their plan for phasing and protecting the area
- Their approach to joint depth and backing
- Proof of insurance
- How long is the guarantee, and what does it include?
Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Colney Street can form part of a wider programme across Hertfordshire.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
What sets the cost
Quotes vary with the job. It mainly depends on:
- Distance, for remote addresses
- The site’s rules and procedures
- Any access equipment needed
- How much existing material needs removing
A quote for facade joints depends on quantities, condition and access. Ask us for a fixed quote.
What we need to price the job
It doesn’t need to be a full survey. These details are enough to start:
- What the building is and how it’s used
- A wide shot and a close-up of the area
- Specification clauses that apply
- When you need the work done
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
Your questions answered
Is The Albert Bygrave Retail Park, near Colney Street, within your area?
Yes. We cover Colney Street and the area around it, including industrial estates, business parks and retail parks such as The Albert Bygrave Retail Park. A few photos and the unit address let us price the work.
Do you take on work at healthcare sites like Kingsley Green Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is old mastic on our building likely to contain asbestos?
For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder. If asbestos is suspected, work stops until it is tested.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Will you check whether the sealant is causing the leak?
Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all, and we will be honest about which it is.
How long does a typical visit take?
That varies with the scale of the job, but the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. If others near Colney Street need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Getting the site ready
- Let building users know which areas are affected
- Share the asbestos register for older buildings
- Agree which areas must stay open

Advice

Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.
