Construction mastic in Chase Cross
Site managers want applicators who turn up with the right cards and paperwork. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we’re fully insured. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. Site teams most often ask us about caulk cracking where joints are moving more than expected and existing joints on a refurb that need cutting out and resealing, across window and door perimeters, cladding and panel joints and sanitary and kitchen joints. For commercial sealant work in Chase Cross, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. Mastic is normally one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What happens if it’s left?
A cheaper sealant can look like an easy saving on a large package. A failed joint in the defects period costs far more than the product difference. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Failed sealant in a building in Chase Cross can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What you get with us
- 12 months’ guarantee on every job
- CHAS accredited contractor
- Colour agreed before work starts
- Public liability insurance in place

What the job involves on each surface
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. Joints are sealed smooth so they’re easy to clean.
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control.
Our process
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes whatever the programme allows, since the work follows the trades as areas are released. For a job in Chase Cross, access comes first. Send the building rules and access times with your enquiry.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Before we start on site
- Tell us what induction or permit system the site runs
- Arrange parking or a loading space
- Share the asbestos register for older buildings

Advice
FAQs: Chase Cross
Do you work in London buildings with loading restrictions?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them. We allow for the ULEZ, which covers every borough
Is a hospital such as Victoria Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you use the sealant named in the specification?
We use the product the specification names. If we think an alternative would suit better, we put it to you first.
Can fire-rated sealing at service penetrations be included?
It can be part of the package where specified. Tell us what records you need and we will confirm with the quote.
What will the job cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Phasing around occupants
- Travel to remote or island sites
- Whether old sealant has to be cut out first
- Induction, permit and paperwork requirements
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Sending details for a quote
However big the job, the same details help:
- A wide shot and a close-up of the area
- What the building is and how it’s used
- Approximate linear metres or a joint schedule
- Asbestos survey details if the building is older
For a fixed quote, phone 01277 525 020 or send details through our quote form. You can also send details through our quote form.
What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Damage to finishes by other trades after we have sealed
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Frame gaps too wide for sealant, which the installer needs to correct
If in doubt, call 01277 525 020 or use the quote form and we’ll say what we think before you book.
Surfaces we seal
- Cladding and panel joints
- Brick and block movement joints
- Sanitary and kitchen joints
- Floor and skirting junctions
- Window and door perimeters
- Internal decorators’ caulk

What else we do in Chase Cross
Mastic packages on Chase Cross sites
The ULEZ covers the whole of Greater London, Chase Cross included, so site vehicles need to meet its standards or pay the daily charge. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. A 2-mile radius around Chase Cross takes in several hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.
New units and refits on sites such as Rom Valley Retail Park (to the south of Chase Cross) need their panel and perimeter joints sealed to the specification. Older buildings in the area around Chase Cross, such as Hare Hall (2 miles south-east of Chase Cross), need care when sealed: the product has to suit soft or historic materials. Hospital estates such as Victoria Hospital, 1.6 miles to the south of Chase Cross, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Site staff or a sealant specialist?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Redoing a failed joint typically costs more than getting it right at the outset, 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.
