A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead, and a backing rod limits the depth to give the sealant room to work. We work on movement joints in walls and floors, window and door perimeters and external facade joints, and what we’re called in for most is wall and floor joints that have lost their seal and mouldy silicone around WCs, urinals and vanity tops. Most enquiries from Primrose Hill start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Occupied buildings in Primrose Hill need the work phased: we agree the order with you and hand back each area with its cure time.
Buildings in a London area such as Primrose Hill rarely close for maintenance: occupied offices, ground-floor retail under residential floors and busy shared entrances. Work is split into zones agreed with the building or facilities manager, so the premises keep working around us, and where a brand finish matters, the sealant colour is agreed first.
We stand by our work: 12 months, guaranteed. That covers our preparation and application.

What we are called out for in Primrose Hill
When a bead peels cleanly off one face, it has failed in adhesion. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. We see it often where joints were sealed in a hurry.
Any of the following is a good reason to get the joints checked over:
- Window and door perimeter joints that have cracked open
- Earlier reseals applied straight onto the failed bead
- Greasy, split joints in a kitchen or tea point
- Black mould through washroom sealant that won’t clean off
Sites a few miles apart, such as Regis Road Business Park and Hannover Industrial Estate, can share one programme and one point of contact.
What your quote should include
- What the guarantee covers, and for how long
- Their public liability cover
- Whether their applicators hold CSCS cards
- Whether primer will be used where the manufacturer specifies it

Other services in Primrose Hill
Diagnose, treat, sign off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a few hours to several days on most single sites, depending on joint lengths and access, and our waste is bagged and taken away as we go. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First, details come to us: photos, drawings or a schedule of the areas.
- We work out why the joints have failed and fix a quote for the agreed scope.
- Before anything is cut out, we agree access, timings and sequence.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- We fit backing to the right depth, prime where specified and lay the new bead.
- Each area is inspected, signed off and backed by our 12-month guarantee.
What we need from you
- Let us know about inductions and permits
- Point out parking and an unloading spot
- Let building users know which areas are affected

Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- A dripping trap, valve or pipe behind a fitting
- Misted, cracked or failed glazing units (a glazier’s job)
- Cracking that needs a structural engineer to look at it
If you’re not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer before you book.

How the job changes by surface
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. The lasting answer is removal, preparation and a new sanitary bead.
Fire-rated seals where specified
Fire-rated sealant is only one type of fire-stopping product. Other products, such as collars, wraps and batts, are specified for different services, and we will tell you if the detail calls for something else.
Questions we’re asked in Primrose Hill
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’ll work to them.
Will our hotel in Primrose Hill need to close for the work?
In the majority of cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Which site documents can you send us?
We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.
Can you take on work for an FM or managing agent?
Yes, and through main contractors too. You send the details, we return a fixed quote, and the job is done and signed off, with a 12-month guarantee on the workmanship.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
What sets the cost
The price varies from site to site. It mainly depends on:
- The site’s rules and procedures
- Working within restricted access windows
- The total length or number of joints
- Which sealant the job calls for
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- Asbestos survey details if the building is older
- Drawings or a marked-up plan, if available
- Any specification or named product
- Anything awkward about access or site hours
Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, speak to us on 01277 525 020 or email the details over.

The 3 miles around Primrose Hill take in at least three named trading estates, business parks or retail parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal; brand colours often come into it.

Offices at parks like Regis Road Business Park (1 mile north-east of Primrose Hill) have receptions, kitchens and glazed partitions where a tidy joint matters.
