Construction mastic across North Ascot
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Whether old sealant has to be cut out first
- Phasing around occupants
- Access and working height
- Travel to remote or island sites
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
What to include in your enquiry
However big the job, these details speed things up:
- Access details, including height
- Any dates the work must fit around
- Rough lengths or quantities, or drawings if you have them
- The asbestos register, for older buildings
The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or email us to discuss it first.

North Ascot: questions and answers
Can you take on a job at a hospital such as Heatherwood Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Can you work around term dates at a campus such as Imperial College Silwood Park Campus?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
What will the job cost?
Every job gets its own fixed quote. To get one, phone 01277 525 020 or email us with a description of the work.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Can you clear a mastic snag list before handover?
Yes. We clear snags by redoing joints rather than patching them to suit the programme.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Can fire-rated sealing at service penetrations be included?
Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. Fire-stopping design and sign-off sit with the designer and building control.

Signs you need construction mastic in North Ascot
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.
Any of the following is a good reason to get the joints checked over:
- Old sealant on a refurbishment that needs stripping before new work
- Sealant knocked or painted over by other trades
- Inconsistent sealant finishes from plot to plot
- Missed perimeter joints on a new elevation
Units on estates such as Ascot Business Park (1.1 miles south-east of North Ascot) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
What to look for in a quote
- Their public liability cover
- Who will actually carry out the work
- Are they CHAS accredited or on Constructionline?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If neighbouring businesses or buildings around North Ascot need work too, visits can be combined. Tell us your site hours and we’ll plan around them.
- We start with the drawings, specification and programme.
- Quantities are measured and a fixed price returned.
- We agree with the site team which areas come first.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
What we need from you
- Let building users know which areas are affected
- For older buildings, check the asbestos register before work
- Let us know about inductions and permits

Why it’s worth doing now in North Ascot
Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go. Snagging can be priced as a separate stage. In a smaller place such as North Ascot, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
Pricing mastic packages depends on quantities, condition and access. Ask us for a fixed quote.

After the work
For the best life from the joints:
- Get the mastic subcontractor involved early in the programme
- Brief the final clean team to avoid blades near sealant
- Protect sealed areas from following trades
- Plan external elevations with the weather in mind
If a joint is damaged after sealing, flag it early. We can return to clear snags before handover.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
