Mastic sealing in Timsbury
Owners and agents usually inherit a building’s mastic rather than choose it, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. If you have estate-wide sealant that is simply worn out and repeated reactive repairs to the same buildings, we can help, whatever the surface. For commercial sealant work in Timsbury, you deal with one contact from quote to sign-off, whether it’s one building or several.
For buildings around smaller places like Timsbury, we group work so one trip covers it. Photos of each elevation help us quote accurately.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Why deal with it now?
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. For buildings around smaller places like Timsbury, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
What you get with us
- 12 months’ guarantee on every job
- Colours confirmed for the specified product
- Old sealant cut out, never sealed over
- Fully insured
See our cost guide or how we’re accredited.
When it isn’t the sealant
Honesty saves time and money. Fresh joints won’t solve:
- Glazing that needs replacing
- Materials that need asbestos testing before work
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think before you book.
Surfaces we seal
- Communal entrances and stairwells
- Window and door perimeters on blocks
- External wall and movement joints
- Shopfronts below residential blocks
- Balcony and threshold joints
- Communal kitchens and washrooms
Planned mastic for Timsbury portfolios
Timsbury sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first. Timsbury lies roughly 69 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
If you’re responsible for a building such as Church of St Andrew, frame and door mastic needs the same attention as any other property. Buildings close to stations like Mottisfont & Dunbridge station (to the west of Timsbury) are often flats over shops, with frame mastic to keep sound. If your remit includes a building such as Stanbridge Earls School, frame and door mastic can be programmed for the holidays.
Timsbury is about 3 miles north-west of Romsey, in Hampshire. Any commercial site in Timsbury is covered. We work across 723 places in Hampshire, from busy centres to rural villages. For work in that direction, see our Southampton page.

Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes a few days for most blocks, with larger programmes scheduled building by building, and we clear our waste as we work. Rural sites near Timsbury may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
Preparing the site
- Tell us your opening times and when work is allowed
- Flag any permit to work we’ll need
- Warn occupants and staff about the work

What the job involves on each surface
Tenement and older buildings
Natural stone can be marked by the wrong sealant and we choose accordingly.
Window and door perimeters on blocks
Blocks have a mix of frame materials, so the grade we pick has to bond to frame and wall alike. Colours are confirmed for the product used.
Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Track which buildings were done and when
- Include mastic in your cyclical inspections
- Share the asbestos register when you send details
- Ask residents or tenants to report leaks and draughts early
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and the complaints that come with it.
Should maintenance staff do it?
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.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
