Construction mastic in Hook
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
How the quote is worked out
These are the things that shape the price:
- Access and working height
- Distance, for remote addresses
- Phasing around occupants
- Removal of failed or old sealant
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Before you send an enquiry
However big the job, the same details help:
- Where the site is, with the postcode
- Whether the building will be occupied during the work
- Drawings or a marked-up plan, if available
- Whether an asbestos survey exists
To get a fixed quote, phone 01277 525 020 or email us, telling us the site location and the nature of the job. Our quote form is another easy route.
Construction mastic in Hook, done properly
Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list and clearing them late eats into the handover window. Our aim is joints that pass at the first inspection, whatever the size of the scheme. If you’re dealing with a mastic package split between trades with no clear owner and a long mastic snag list close to completion, we can help, on window and door perimeters, brick and block movement joints and sanitary and kitchen joints alike. A single leaking joint is often how a building in Hook first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a site near Hook, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photos and the programme let us give a fixed quote.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

When to bring in a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Certain joints really need a specialist: 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.
On site: what to expect
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes whatever the programme allows, since the work follows the trades as areas are released, and we clear our waste as we work. If others near Hook need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- We price from the drawings, specification and programme you send.
- You receive a fixed quote listing scope, products and phasing.
- 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.
Getting the site ready
- Tell us what induction or permit system the site runs
- Tell us which areas need to stay in use

Looking after the joints
For the best life from the joints:
- Allow flexibility for external sealing in damp or cold weather
- Release areas for mastic once other trades have finished in them
- Keep finished joints away from paint, plaster and scrapers
- Share drawings and the specification as soon as possible
At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later. We can confirm the handover information you need when we quote.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.
Hook: questions and answers
Do you cover business parks and estates near Hook, such as Kite's Croft Business Park?
Yes, sites like Kite's Croft Business Park are within our area, along with the rest of Hook. Send details of the unit and the work through our quote form for a quick quote.
Would you work within a site like Fareham Community Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
What joints do you seal on a new build?
Window and door perimeters, internal decorators’ caulk where specified, sanitary joints, kitchens, movement joints and snagging. We price to the specification and drawings.
How do you work with the site programme?
Our work is sequenced around the programme. Each plot, floor or elevation is sealed when it’s ready.
Can you send site paperwork?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Faulty frames rather than failed sealant
- Rework caused by others damaging completed areas
- Joint design decisions that belong to the architect or engineer
Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we’ll tell you honestly.
Surfaces we seal
- Window and door perimeters
- Brick and block movement joints
- Cladding and panel joints
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Floor and skirting junctions
Leave it or put it right?
When a package runs over budget, downgrading the product is a common first thought. A failed joint in the defects period costs far more than the product difference, especially externally. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Converted and older buildings near places like Hook tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
What you get with us
- Our applicators hold CSCS cards
- CHAS accredited
- 12-month guarantee on workmanship
- A range of standard colours, depending on the product

New build and refits around Hook
With the shore within about 1 mile, Hook counts as a coastal location. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. A 2-mile radius around Hook takes in several hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
Extensions at sites like Fareham Community Hospital (to the north of Hook) typically sit beside working departments, and the mastic follows strict access rules. For contractors refurbishing units at places like Kite's Croft Business Park, 1.5 miles north-east of Hook, the mastic covers cladding panels, roller-door and window perimeters. School extensions, at buildings such as Locks Heath Infant School, typically run to the summer holidays, mastic included.
