When to call us in Street End
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and it tears.
Common reasons buildings call us in:
- No planned programme for sealant
- Estate-wide sealant that is simply worn out
- Old repairs sealed over failed mastic
- Cracked, hardened mastic round windows on a block
For a school such as Sidlesham Primary School, perimeter mastic on windows and doors is a holiday job.

Mastic sealing in Street End, done properly
Owners and agents normally 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 along with complaints. We work on external wall and movement joints, balcony and threshold joints and communal kitchens and washrooms, and what we’re called in for most is draught complaints from residents or tenants and damaged joints in communal entrances and corridors. Facilities teams, main contractors and managing agents in Street End tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Owners and agents with buildings around smaller places such as Street End tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
A 12-month guarantee applies to all our work. If an installation problem shows up, give us a call on 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

Mastic sealing in Street End: the local picture
Street End lies within about 2 miles of the sea. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints. At about 58 miles from central London, Street End is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate.
If you own or manage units on a site such as Enborne Business Park, 1.5 miles south of Street End, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Trustees of buildings like St Mary Our Lady Sidlesham can bring frame and external mastic into a planned maintenance list.
Street End is about 4 miles north of Selsey, in West Sussex. Our applicators travel to Street End for work on mastic joints, handled exactly as we handle every other area. Street End is one of 373 places we cover in West Sussex for mastic joints. Portsmouth is covered too, around 13 miles from Street End.

On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Street End can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
What we need from you
- Let building users know which areas are affected
- Point out any areas we must not close
- Flag any permit to work we will need

Advice
When something else is needed
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Leaks from above rather than through a joint
- Failed window or door frames, which need a window contractor
- Asbestos-containing sealant, which we don’t remove
If you’re not sure, just give us a call on 01277 525 020 or email us and we’ll give you a straight answer.
Joints and surfaces we work on
- Communal entrances and stairwells
- Communal kitchens and washrooms
- External wall and movement joints
- Window and door perimeters on blocks
- Balcony and threshold joints
- Shopfronts below residential blocks
When to bring in a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Leave it or put it right?
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. For buildings around smaller places like Street End, 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. Renewing joints in good time avoids the problem.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

What guarantee do you give on resealing?

Is asbestos a concern with old mastic?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Is Street End in your area?
Yes. Street End is in our area, within our coverage of Greater London, South East England and Scotland. For a quote, speak to us on 01277 525 020 or email the details over.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
