What sealant work can’t fix
Being straight saves everyone time. New sealant won’t cure:
- Deciding which fire-stopping product a penetration needs
- Joints damaged after sign-off by following trades
- Designing joint widths or choosing the specification (that sits with the designer)
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we will tell you honestly before you book.

Construction mastic in Holloway
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal sealing often fills those days. We work on window and door perimeters, cladding and panel joints and sanitary and kitchen joints, and what we are called in for most is new external sealant already peeling away and frame gaps too wide for sealant alone. A specialist sealant contractor works differently from a general builder: on jobs in Holloway, preparation and product choice get the time they need.
Construction in and around smaller places such as Holloway is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Mastic packages on Holloway sites
At about 30 miles from central London, Holloway is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.
Projects at colleges like Berkshire College of Agriculture, 1.1 miles to the north-west of Holloway, tend to run to term dates, so the mastic is planned tightly. Hotels like Hurley House Hotel, 1.2 miles north of Holloway, rarely close for long, so refurbishment mastic is phased floor by floor. Projects at schools like Burchetts Green CofE Infants' School work to term dates, so mastic is programmed tightly.

Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.
Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Keep product details for future maintenance
- Brief following trades on areas that have been sealed
- Ask for joint and product checks before the package is urgent
- Ask installers to correct oversized gaps first
Once an area is sealed, protect it from following trades. 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. Water gets behind trays, vanity tops and panels, and the repair falls into the defects period. Getting the product and preparation right first time avoids that.
On site: what to expect
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself typically taking whatever the programme allows, since the work follows the trades as areas are released. For a building around Holloway, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised straight away.
- Final snagging is completed and the 12-month guarantee applies.
What we need from you
- Make sure the joints can be reached
- Send your site hours and access windows
- Tell us which areas need to stay in use

Common questions from Holloway clients
Will you take on work at estates like Maidenhead Business Park, close to Holloway?
Yes, sites like Maidenhead Business Park are within our area, along with the rest of Holloway. Photos and a short description are enough for a first look.
Will you plan work around the academic year at somewhere like Berkshire College of Agriculture?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
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, flagging anything that needs clarifying.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What accreditations do you hold?
We are CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. We confirm any paperwork you need with the quote.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Different surfaces, different methods
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification, with backing rod in deeper gaps.
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. Snagging can be included or priced separately.
What affects the price in Holloway
There’s no standard rate for sealant work, because every site is different. What we look at:
- Access and working height
- Working within restricted access windows
- The site’s rules and procedures
- Backing rod, priming and other preparation
A quote for mastic packages 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
It doesn’t need to be a full survey. A few details are enough to get going:
- How the joints are reached, and at what height
- The type of building and who uses it
- Whether an asbestos survey exists
- Your programme or deadline
The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or speak to us on 01277 525 020 or send photos by email if you’d rather talk the job through.
