Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Site maintenance staff can often handle a short internal joint. 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.
Mastic sealing in Waterlooville
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable. We will confirm the colours available for the specified product. Most enquiries involve occupiers reporting cold air round windows and damp patches beside frames, on shopfronts below residential blocks, communal entrances and stairwells and communal kitchens and washrooms. Whoever orders the work in Waterlooville, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Towns the size of Waterlooville have a mix of blocks, flats over shops and small commercial buildings looked after by agents and landlords. Mastic around frames, external joints and communal doors ages and needs renewing.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Keeping the joints sound
To get the most from the new sealant:
- Have the asbestos survey to hand for older buildings
- Plan resealing building by building rather than complaint by complaint
- Log resealing dates block by block
- Reduce knocks to communal area joints
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.
Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a few days for most blocks, with larger programmes scheduled building by building, and our waste is bagged and taken away as we go. Town-centre premises in Waterlooville may have limited parking, so tell us what’s nearby. Industrial and business units normally have yard or car park space.

- The joints are prepared and resealed with the right product.
- We finish each building before moving to the next.

Frames, entrances and external joints in Waterlooville
Waterlooville lies within about 3 miles of the sea. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. Waterlooville is about 59 miles from central London. Managed blocks of flats are a big part of commuter-belt property.
With historic buildings such as Warblington Castle, 4 miles to the south-east of Waterlooville, in the wider area, owners of older properties around Waterlooville should expect mastic to need a product that suits old masonry. If you are responsible for a building such as Saint George's, frame and door mastic needs the same attention as any other property. Buildings close to stations like Bedhampton station (2.6 miles south-east of Waterlooville) are often flats over shops, with frame mastic to keep sound.

What happens if it’s left?
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once, under a single quote and a single programme. A failed joint is easier to put right before damp shows inside. After a leak, there’s drying, repairs and redecoration on top.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote when you’re ready.

Waterlooville: questions and answers
Can being near the sea in Waterlooville affect the sealant we need?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.
Will you take on work at estates like Dunsbury Hill Business Park, close to Waterlooville?
Yes. We cover Waterlooville and the area around it, including industrial estates, business parks and retail parks such as Dunsbury Hill Business Park. To start, just call 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Can you reseal a whole block or estate?
Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.
Do you guarantee the mastic work?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
Can you quote from photos?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.
Do you cover Waterlooville?
Yes. Waterlooville falls within our area, and you can call 01277 525 020 or send details through our quote form to get started.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Owners, agents and contractors
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Quoting for work in Waterlooville
Each job is priced on its own details. The things that drive the figure:
- How much existing material needs removing
- Distance, for remote addresses
- Backing rod, priming and other preparation
- Specialist products, such as fire-rated or hygienic sealants
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
