Mastic sealing in Hook
Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. We work on shopfronts below residential blocks, communal entrances and stairwells and balcony and threshold joints, and what we’re called in for most is window mastic that has split and shrunk and the same joint failures repeated across a portfolio. For commercial sealant work in Hook, you deal with one contact from quote to sign-off, whether it’s one building or several.
For owners with a single building near Hook, we plan to finish in one visit where possible. Send photographs of the frames and joints and we will give a fixed quote.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Keep bins and bikes away from communal door frames
- Plan resealing building by building rather than complaint by complaint
- Look at the sunniest and most exposed elevations first
- Share your contractor requirements early
Keep records of when each building was resealed. It helps plan the next round and gives you a history.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and the complaints that come with it.
Your questions answered
Will you take on a block within reach of Swanwick station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Will you take on work at estates like Kite's Croft Business Park, close to Hook?
Yes. Our area takes in Hook and its surroundings, with estates and business parks such as Kite's Croft Business Park included. Photos and a short description are enough for a first look.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
Do you supply RAMS and insurance details?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do you work with property factors and landlords?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
Why deal with it now?
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. One visit to deal with every failing joint makes more sense than several trips to a place like Hook. Photos of every joint help us quote for the whole job.
A quote for mastic joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

Different surfaces, different methods
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies and tend to fail first.
Tenement and older buildings
Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.
From enquiry to sign-off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. Smaller jobs around Hook can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
What we need from you
- Make sure the joints can be reached
- Share your working hours and any access restrictions
- Tell staff and tenants when we’ll be in

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

General trades versus a specialist
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Frames that are rotten, warped or broken
- Substrate edges that need repairing first
- Broken glass or failed sealed units
If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.
Surfaces we seal
- Communal kitchens and washrooms
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- Communal entrances and stairwells
- External wall and movement joints
- Balcony and threshold joints
Blocks and managed buildings in Hook
Hook sits close to the coast, within about 1 mile. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, and they deserve more regular inspection. Hook is about 68 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.
Schools and community buildings such as Locks Heath Infant School need frame and external mastic kept sound like any building. Churches, halls and community buildings such as Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. For agents with blocks near Swanwick station (2.2 miles north of Hook), a block-wide mastic programme deals with frames, balconies and entrances in one go.
