Questions we are asked in Tide Mills
Do you cover business parks and estates near Tide Mills, such as Newhaven Industrial Park?
Yes. We cover Tide Mills and the area around it, including industrial estates, business parks and retail parks such as Newhaven Industrial Park. To start, just ring 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Will you take on a block within reach of Bishopstone (Sussex) station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
Do you do block-wide mastic programmes?
Yes. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you supply RAMS and insurance details?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Mastic sealing for commercial buildings in Tide Mills
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. The enquiries we see most involve leaks at window and door perimeters and movement joints with sealant missing, across communal entrances and stairwells, balcony and threshold joints and external wall and movement joints. A single leaking joint is often how a building in Tide Mills first comes to us: we look at the rest while we’re there and tell you what we find.
In and around smaller places like Tide Mills, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Plan resealing building by building rather than complaint by complaint
- List the paperwork your organisation requires when you send details
- Have the asbestos survey to hand for older buildings
- Make it easy for occupiers to report draughts
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
One failed perimeter normally means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
Why deal with it now?
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes and those cost far more to put right. Converted and older buildings near places like Tide Mills tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Signs you need mastic sealing in Tide Mills
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant and the repair soon fails.
These are often picked up first by site or facilities staff:
- Water getting in round frames after rain
- Open joints in brickwork or panels
- A mix of products and colours from past repairs
- Repeated reactive repairs to the same buildings
If you are responsible for a building such as Church of St Andrew, frame and door mastic needs the same attention as any other property.
What your quote should include
- How the existing material will be dealt with
- What the guarantee covers, and for how long
- Whether their applicators hold CSCS cards
- Are they CHAS accredited or on Constructionline?
Honest limits
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Leaks from above rather than through a joint
- Frames that are rotten, warped or broken
- Materials that need asbestos testing before work
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
What we seal

How the job changes by surface
Estate-wide resealing programmes
Consistent products and colours across an estate make future maintenance simpler.
Tenement and older buildings
Natural stone can be marked by the wrong sealant, so we pick a grade that won’t mark it.
