How we handle mastic sealing in Boorley Green
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. If you are dealing with window mastic that has split and shrunk and patchy repairs in mismatched sealant, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Boorley Green it comes down to the same thing: the right product in a properly prepared joint.
Converted and older buildings in and around Boorley Green often put modern windows into old walls. The mastic there needs to suit both surfaces.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

What happens if it’s left?
Failed perimeter mastic lets cold air in around frames and the windows normally get the blame. Resealing the perimeters is often the simpler fix where the frames themselves are sound. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Common questions from Boorley Green clients
Can you quote for a block close to Hedge End station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Is a smaller place like Boorley Green outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Can you reseal a whole block or estate?
Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.
Surface by surface
Communal areas
We keep entrances and stairs open throughout. Work is planned in sections.
Planned maintenance
Adding mastic to planned maintenance avoids reactive repairs and spreads the work.
How a job runs
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If neighbouring businesses or buildings around Boorley Green need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
What we need from you
- Warn occupants and staff about the work
- Tell us what induction or permit system the site runs
- Point out any areas we must not close

Frames, entrances and external joints in Boorley Green
Rainfall across the South East, Boorley Green included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. At about 65 miles from central London, Boorley Green is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide.
Historic properties like South Stoneham House (4.3 miles west of Boorley Green) show the age of some local stock, where frame mastic must suit soft brick or stone. Blocks of flats and mixed-use buildings often cluster around stations such as Hedge End station, 0.7 miles west of Boorley Green, and their window and balcony mastic tends to age at the same rate across a building.
Boorley Green is about 1 mile north-east of Hedge End, in Hampshire. Anywhere in SO32, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Boorley Green is one of 723 places we cover in Hampshire.
