About our mastic sealing in Bishopstoke
Older blocks and commercial buildings can have mastic that contains 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. We don’t remove asbestos-containing materials. We work on shopfronts below residential blocks, external wall and movement joints and balcony and threshold joints, and what we are called in for most is draughts at frames across a block and estate-wide sealant that is simply worn out. Whether you call it commercial sealant work, mastic application or joint sealing, in Bishopstoke it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Converted and older buildings in and around Bishopstoke often put modern windows into old walls. The mastic there needs to suit both surfaces.
Our workmanship is guaranteed for 12 months, in Bishopstoke as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What we’re called out for in Bishopstoke
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks, especially on south and west faces.
It’s worth sending us details if you spot any of the following:
- Water getting in round frames after rain
- Communal area joints that look neglected
- Estate-wide sealant that is simply worn out
- Complaints coming in block by block
If you manage student housing near a university such as University of Southampton, which lies south-west of Bishopstoke, the summer turnaround is the time for mastic.
What to look for in a quote

When something else is needed
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Asbestos-containing sealant, which we don’t remove
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Broken glass or failed sealed units
If you’re not sure, just call the office on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

What the job involves on each surface
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
External movement joints
The joint width has to suit the movement and the sealant’s capability, often around 2:1 width to depth, as the manufacturer advises.
Leave it or put it right?
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. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
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 are ready.

Frames, entrances and external joints in Bishopstoke
The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. At about 65 miles from central London, Bishopstoke is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property.
Blocks of flats and mixed-use buildings often cluster around stations such as Eastleigh station, 1 mile west of Bishopstoke, and their window and balcony mastic tends to age at the same rate across a building. Trustees of buildings like St Paul's can bring frame and external mastic into a planned maintenance list.
Bishopstoke is about 1 mile east of Eastleigh, in Hampshire. We cover Bishopstoke, with the same fixed quotes and 12-month guarantee as everywhere else. Bishopstoke is one of 723 places we cover in Hampshire.

Your questions answered
Is a smaller place like Bishopstoke outside your area?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Do you work for managing agents with blocks near Eastleigh station?
Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Can you send RAMS and CSCS details before starting?
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.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Can you plan resealing across several buildings?
Yes. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
How the quote is worked out
We price every job individually. The main factors are:
- Which sealant the job calls for
- Quantities, in metres or numbers
- Removal of failed or old sealant
- The size and state of each joint
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
- Asbestos survey details if the building is older
- The site address and postcode
