Building owners, agents and FMs in Forestside
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Forestside can form part of a wider programme across West Sussex.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
About our mastic sealing in Forestside
Across Forestside and the rest of West Sussex, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote, and site visits can be arranged. If you have open joints in brickwork or panels and communal area joints that look neglected, we can put it right, on communal entrances and stairwells, external wall and movement joints and balcony and threshold joints alike. A specialist sealant contractor works differently from a general builder: on jobs in Forestside, preparation and product choice get the time they need.
Rural conversions near places like Forestside 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.
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.

Our process
Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Forestside are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Getting the site ready
- Tell us your opening times and when work is allowed
- Have the specification and drawings to hand
- Send asbestos survey details if the building is pre-2000
Quotes
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

How the job changes by surface
External movement joints
Brickwork, blockwork and panel joints let a building move. Once that sealant goes, rain can reach the wall.
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
Site staff or a sealant specialist?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Questions we are asked in Forestside
Can one quote cover a number of our buildings near Forestside?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photographs and we will give a fixed quote.
Is Forestside too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.
Do you guarantee the mastic work?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
How long will the new sealant last?
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.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
What happens if it’s left?
Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work with less control over timing. Around Forestside, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Frames, entrances and external joints in Forestside
Central London is about 54 miles from Forestside. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate. Forestside sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Older buildings near Forestside, from historic houses such as Uppark, 3.2 miles north of Forestside, to more modest stock, need compatible products when frames are resealed. If you look after a block within reach of Rowlands Castle station, 2.2 miles south-west of Forestside, frame and balcony mastic can be renewed on one programme. Older community buildings, Christ Church among them, often have frames of mixed ages whose mastic varies.
