About our commercial sealant contractors in Colindale
If you look after more than one building, a single sealant contractor saves a lot of chasing. Single jobs, multi-site packages and planned programmes all come to us, run the same way on every site: details in, a fixed quote back, the sealing done, then our 12-month guarantee. To get a programme moving in Colindale, ring 01277 525 020 or email drawings and photos with the site addresses. If you have leaks that seem to come through a sealant line and wall and floor joints that have lost their seal, we can put it right. A single leaking joint is often how a building in Colindale first comes to us: we look at the rest while we’re there and tell you what we find.
On a typical commercial building in Colindale, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.
Buildings in a London area such as Colindale 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.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

When to call us in Colindale
Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed. BS 6213 gives guidance on choosing construction sealants.
These are often picked up first by site or facilities staff:
- Hardened, chalky sealant on south-facing or exposed elevations
- Messy, uneven beads from earlier work that let the building down
- Mouldy silicone around WCs, urinals and vanity tops
- Earlier reseals applied straight onto the failed bead
Like every part of Greater London, Colindale is covered by the ULEZ, so vehicle access, loading and parking are planned before the first visit.

Work for main contractors and building owners
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Colindale can sit alongside others in a wider programme.
Your questions answered
Is Colindale Retail Park, near Colindale, within your area?
Yes. Estates, retail parks and business parks around Colindale, Colindale Retail Park among them, are all within reach. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Does a hotel in Colindale need to shut while its sealant is renewed?
Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.
How do we get a quote?
The main factors are metres of joint, removal, access, the product and how many phases there are. For a fixed quote, send details through our quote form.
What guarantee do you give on resealing?
A 12-month guarantee covers the workmanship. Keeping joints clean and inspected helps them last well beyond that.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Can you handle sealant work across several sites?
Yes, within the areas we cover: South East England, Greater London and Scotland. Each site gets the same process and a single contact.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Frontages, fit-outs and joints in Colindale
At least three named trading, business or retail sites lie within about 3 miles of Colindale. Sites like these see regular refits, with shopfronts, offices and staff areas to seal; brand colours often come into it. London premises normally come with a building manager, booked loading and house rules for contractors. We work within them, one zone at a time.
A hotel such as Hendon Hall Hotel (to the east of Colindale) shows how much sealant a hospitality building has on show, from bathroom joints to the bar. For premises near Hendon station, 1 mile to the south-east of Colindale, footfall is part of the plan: work is phased so shops and offices keep trading.

What’s near Colindale
Around Colindale, our work takes us to commercial buildings near Sunny Hill Park, Saracens High School and Kisharon College and the streets around them. The nearest railway station is Hendon station, about 1 mile south-east of the centre. Nearby you’ll also find Edgware Community Hospital (1.3 miles north-west) and Brent Cross Shopping Centre (1.5 miles south-east). Not far away are Darland's Lake and Parliament Hill.
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Water from a services leak rather than a joint
- Structural cracks or movement the joints weren’t designed for
Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking as long as the agreed scope needs, from a single visit to a programme spread over several weeks. Planning a London job such as one in Colindale starts with access. Send the building rules and access times with your enquiry.
- Send details through our quote form, or ask for a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
Getting the site ready
- Tell us which areas need to stay in use
- Share the asbestos register for older buildings
- Arrange parking or a loading space
Ask for a quote
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

What sets the cost
Before we quote, we look at:
- Quantities, in metres or numbers
- Travel to remote or island sites
- Removal of failed or old sealant
- The size and state of each joint
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Your programme or deadline
- Rough lengths or quantities, or drawings if you have them
- Access details, including height
- The type of building and who uses it
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
