About our coloured sealant in North Finchley
Architects, designers and brand teams often specify the sealant colour as carefully as the finishes around it. Standard sealant ranges cover many colours, so we check what the specified product is made in at quote stage. We don’t promise an exact custom match, but we’ll show you the closest options. If you have previous reseals that don’t match the original and discoloured joints on a visible elevation, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in North Finchley is the same: the right product in a properly prepared joint.
Much of the planning for a London commercial job is about getting in and out: booked loading, goods-lift times, the permit system and a place to stage materials. With access agreed, we work through the colour-matched joints a section at a time, keeping disruption to tenants low.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

How a job runs
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. In North Finchley, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- Photos or drawings show us the finishes and joints.
- We send the closest colours from the product’s range.
- The programme and access are agreed, including any phasing.
- We prepare each joint, prime where needed and fit backing.
- The agreed colour is installed and tooled neatly.
Preparing the site
- For older buildings, check the asbestos register before work
- Explain the parking and delivery arrangements
- Tell us your opening times and when work is allowed

Common questions from North Finchley clients
Must a hotel around North Finchley close while you work?
Almost never. The work is phased so most rooms stay available. We agree the order of rooms and the timings with you before we start.
Can you work at a site such as Finchley Industrial Centre, by North Finchley?
Yes. We cover North Finchley and the area around it, including industrial estates, business parks and retail parks such as Finchley Industrial Centre. A few photos and the unit address let us price the work.
Do you use coloured sanitary silicone?
Yes. Wet-area sealants are made in colours as well as white. We will confirm what’s available for the specified product before work starts.
Will the sealant be an exact match to our finish?
No, not in every case. We match as closely as the product’s range allows and can agree a sample bead first.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
What the job involves on each surface

Quoting for work in North Finchley
These are the things that shape the price:
- Location, for remote and island sites
- Backing rod, priming and other preparation
- How accessible the joints are
- Quantities, in metres or numbers
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.
Sending details for a quote
Whether it’s one area or a whole building, the same details help:
- Any specification or named product
- The postcode of the building
- Clear photos of the problem areas
- What the building is and how it’s used
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.
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Record the product and colour reference on the building file
- Put the colour reference on the finishes schedule
- Protect fresh coloured sealant from dust and handling
- Approve a sample bead on high-profile areas
Don’t let anyone patch a coloured joint with whatever sealant is to hand. A mismatched repair stands out.
Put the sealant colour into the specification or finishes schedule. Late decisions lead to substitutes and mismatches, so agree it with the designer at the start.
Leave it or put it right?
Matching new joints to the existing ones is easier when the whole run is done together. Small repairs at different times rarely match, so a planned reseal often looks better value. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
