Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. All of Greater London is in the ULEZ, and kerbside space in Chalk Farm can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- We check the finished work and confirm the guarantee.
Before we start on site
- Tell us which areas need to stay in use
- Point out parking and an unloading spot
- Flag any permit to work we will need

Advice
Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Quoting for work in Chalk Farm
These are the things that shape the price:
- Location, for remote and island sites
- Any access equipment needed
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
Pricing mastic joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.
What to include in your enquiry
A good diagnosis starts with the right details. Tell us:
- Whether the building will be occupied during the work
- Any specification or named product
- How the joints are reached, and at what height
- A wide shot and a close-up of the area
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.
What we’re called out for in Chalk Farm
Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified it comes away from one face.
These are often picked up first by site or facilities staff:
- Patchy repairs in mismatched sealant
- Window mastic that has split and shrunk
- Water getting in round frames after rain
- Draught complaints from residents or tenants
Site managers at schools like Haverstock School can fit frame mastic into the summer works.
Before you book anyone
- Do they follow the manufacturer’s priming guidance?
- How joint depth will be controlled
- Who will actually carry out the work
- What site paperwork they can supply

FAQs: Chalk Farm
Can you cope with the access rules in a London building?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Can you work at a site such as Regis Road Business Park, by Chalk Farm?
Yes. Estates, retail parks and business parks around Chalk Farm, Regis Road Business Park among them, are all within reach. A few photographs and the unit address let us price the work.
Will residents or tenants be disturbed?
The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
What paperwork can you provide?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
