How we handle construction mastic in Jericho
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. One contractor for all of it keeps the responsibility in one place. Most enquiries involve different trades sealing to different standards and cracks opening in caulked internal joints, across cladding and panel joints, floor and skirting junctions and window and door perimeters. A single leaking joint is often how a building in Jericho first comes to us: we look at the rest while we are there and tell you what we find.
In a smaller place such as Jericho, construction tends to mean small housing schemes, conversions and extensions to community buildings. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
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.

New build and refits around Jericho
At about 53 miles from central London, Jericho is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. Jericho has plenty of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Hotels like The Jericho Hotel, less than half a mile to the south of Jericho, rarely close for long, so refurbishment mastic is phased floor by floor. Extensions at sites like Warneford Hospital (to the east of Jericho) normally sit beside working departments, and the mastic follows strict access rules. Units on estates such as Littlemead Business Park (0.8 miles south-west of Jericho) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

From enquiry to sign-off
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. Several jobs near Jericho can be grouped on one trip. Mention the building’s opening times and we will work within them.
- First we take quantities off the drawings and read through the specification.
- We return a fixed quote that ties the mastic package to your programme.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- We seal each plot or floor as it’s released to us.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- We close out snagging and hand over with a 12-month guarantee.
Before we start on site
- Make sure the joints can be reached
- Send your site hours and access windows
- Tell us what induction or permit system the site runs

Related advice
Surface by surface
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. We use the specified perimeter sealant, usually a low-modulus neutral-cure silicone.
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. Joints are sealed smooth so they’re easy to clean.
When something else is needed
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Frames fitted out of tolerance
- Faulty frames rather than failed sealant
- Designing joint widths or choosing the specification (that sits with the designer)
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly.
Surfaces we seal
- Floor and skirting junctions
- Window and door perimeters

Your questions answered
Do you take on work at healthcare sites like Warneford Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Does your area include sites such as Littlemead Business Park, near Jericho?
Yes. Our area takes in Jericho and its surroundings, with estates and business parks such as Littlemead Business Park included. Photos and a short description are enough for a first look.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Do you need to see the site first?
It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
What do you charge?
We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.
Looking after the joints
A few simple habits keep the new joints working:
- Put any product change through the designer first
- Keep product details for future maintenance
- Protect sealed areas from following trades
- Ask installers to correct oversized gaps first
After we’ve sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby; we confirm the time for each product.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, and the repair falls into the defects period. Getting the product and preparation right first time avoids that.
Doing it in-house
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
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.
What else we do in Jericho
Why act early in Jericho
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple. In a smaller place such as Jericho, 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.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
