About our mastic sealing in Hambrook
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. We work on balcony and threshold joints, communal kitchens and washrooms and external wall and movement joints, and the usual reasons a site gets in touch are mastic failing across several blocks on an estate and leaks at window and door perimeters. For commercial sealant work in Hambrook, you deal with one contact from quote to sign-off, whether it’s one building or several.
Rural conversions near places like Hambrook often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

How a job runs
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. Jobs in and around smaller places like Hambrook are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Getting the site ready
- Tell us your opening times and when work is allowed
- Tell staff and tenants when we will be in
- For older buildings, check the asbestos register before work
Getting a fixed quote
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Mastic sealing around Hambrook: what changes locally
Hambrook is within about 2 miles of the coast. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first; plan inspections around that. Hambrook is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.
If you look after a block within reach of Nutbourne station, 0.6 miles south of Hambrook, frame and balcony mastic can be renewed on one programme. If you own or manage units on a site such as Hambrook Business Park, which lies north of Hambrook, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. For a school such as Chidham Parochial Primary School, perimeter mastic on windows and doors is a holiday job.
Hambrook is about 5 miles west of Chichester, in West Sussex. We cover commercial sites throughout Hambrook, whether it’s a single job or part of a planned programme.

Honest limits
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Asbestos-containing sealant, which we don’t remove
- Misted or failed double-glazed units
If you’re not sure, just speak to us on 01277 525 020 or email drawings and photos and we will give you a straight answer.
What we seal
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Communal entrances and stairwells
- External wall and movement joints
- Balcony and threshold joints
Doing it in-house
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Questions about Hambrook
Can you work in a care home near Hambrook with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.
Can you quote for a block close to Nutbourne station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
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.
How the job changes by surface
Estate-wide resealing programmes
A programme can start with the worst buildings and work down. Quotes can be per block or for the full programme.
Tenement and older buildings
Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.
What happens if it’s left?
Dealing with failed joints one report at a time is slow and scattered. Planned resealing covers a whole building or estate in one go, under a single quote and a single programme. Around Hambrook, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
