When to call us in Thorley
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone and the repair soon fails.
Most enquiries start with one or more of the following:
- Draughts at frames across a block
- Failed external movement joints
- Water getting in round frames after rain
- Cracked, hardened mastic round windows on a block
Older buildings near Thorley, from historic houses such as Mottistone Manor (to the south-east of Thorley) to more modest stock, need compatible products when frames are resealed.

About our mastic sealing in Thorley
Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. If you are dealing with old repairs sealed over failed mastic and mastic failing across several blocks on an estate, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Thorley is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Owners and agents with buildings around smaller places such as Thorley 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.

Why it’s worth doing now in Thorley
Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Older rural buildings around Thorley move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.
Why appoint us
- 12-month guarantee on workmanship
- One phone line for London, the South East and Scotland
- Matching to RAL references, product permitting
- Specification-led, product-correct work

Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Thorley are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

Related advice
Thorley: questions and answers
Does the sea air around Thorley change the choice of sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is Thorley too small for you to travel to?
Not at all. Thorley is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Do you work for managing agents and housing associations?
Yes. 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.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Is asbestos a concern with old mastic?
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.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
What paperwork can you provide?
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 will confirm with the quote.
For managing agents and facilities managers
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Block-wide mastic in Thorley
Thorley is within about 2 miles of the coast. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, so it’s worth inspecting those sides more often. Thorley sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.
Buildings close to stations like Lymington Pier station (to the north-west of Thorley) are often flats over shops, with frame mastic to keep sound. If you’re responsible for a building such as St. Swithin's Church, frame and door mastic needs the same attention as any other property.
