About our mastic sealing in Hillstreet
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. If you have repeated reactive repairs to the same buildings and failed external movement joints, we can put it right. Looking for mastic applicators who cover Hillstreet? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Owners and agents with buildings around smaller places such as Hillstreet tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

How a job runs
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Hillstreet can be grouped with others nearby. A fixed quote is given before anything starts.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
Getting the site ready
- Tell staff and tenants when we will be in
- Share the asbestos register for older buildings
- Clear stock, furniture or equipment away from the joints

Looking after the joints
Once the work is signed off, these steps help:
- Start inspections with the most exposed faces
- Encourage occupiers to report problems at frames
- Group repairs into a planned programme
- Make mastic part of routine maintenance checks
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.
Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order and work down the list.
What we’re called out for in Hillstreet
The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
Any of the following is a good reason to get the joints checked over:
- Patchy repairs in mismatched sealant
- Worn sealant at communal door frames
- Cracked, hardened mastic round windows on a block
- Occupiers reporting cold air round windows
For a school such as Calmore Junior School, perimeter mastic on windows and doors is a holiday job.

Mastic sealing around Hillstreet: points for this area
Hillstreet lies within about 3 miles of the sea. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, and they deserve more regular inspection. Seven care or nursing homes sit less than 2 miles from Hillstreet. Owners of care premises can bring window and door mastic into a phased programme planned around the home.
If you look after a block within reach of Totton station (2.3 miles south-east of Hillstreet), frame and balcony mastic can be renewed on one programme. Older community buildings, St Anne's among them, often have frames of mixed ages whose mastic varies.
Hillstreet is about 2 miles north of Totton, in Hampshire. Across the SO40 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Hampshire coverage takes in 723 places. Southampton is covered too, some 6 miles away.
Commercial sites across SO40 are covered. Nearby places we also cover include Ower (1 mile west), Wigley (1 mile north-west), Totton (2 miles south), Winsor (2 miles south-west) and Netley Marsh (2 miles south) for mastic joints. Nearby towns on our patch include Winchester (12 miles north-east), Eastleigh (8 miles east), Fareham (15 miles south-east), Chandler's Ford (6 miles north-east), Hedge End (9 miles east) and Lymington (13 miles south).
What’s near Hillstreet

Why deal with it now?
Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish. Older rural buildings around Hillstreet move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you’re ready.

When something else is needed
Being straight saves everyone time. Fresh joints won’t solve:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Water coming in from the roof or rainwater goods
- Leaks through the frame itself rather than the perimeter
If in doubt, speak to us on 01277 525 020 or send details through our quote form and we’ll say what we think.
Joints and surfaces we work on
- Shopfronts below residential blocks

- Window and door perimeters on blocks
- Communal entrances and stairwells
Should maintenance staff do it?
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.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Questions we’re asked in Hillstreet
Will you work in a care home in Hillstreet without moving residents out?
Yes, with the manager deciding the order and timing of rooms. We follow the home’s own procedures throughout.
Does your area include sites such as South Hampshire Industrial Park, near Hillstreet?
Yes, sites like South Hampshire Industrial Park are within our area, along with the rest of Hillstreet. Photos and a short description are enough for a first look.
Do you guarantee the mastic work?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Do you work for managing agents and housing associations?
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 we quote building by building or as a programme.
What’s the quickest route to a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
