Construction mastic in Baybridge
On refurbishments, the mastic package typically includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old, and on older buildings we ask for the asbestos survey before disturbing anything. After that, the joints are prepared and sealed to the specification. We work on window and door perimeters, internal decorators’ caulk and brick and block movement joints, and the usual reasons a site gets in touch are a mastic package split between trades with no clear owner and perimeter gaps outside the sealant’s range. A single leaking joint is often how a building in Baybridge first comes to us: we look at the rest while we are there and tell you what we find.
Around smaller places like Baybridge, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Our process
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Baybridge need work, visits can be combined. A fixed quote is given before anything starts.
- Drawings, the sealant specification and your programme come to us for pricing.
- You receive a fixed quote listing scope, products and phasing.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- We close out snagging and hand over with a 12-month guarantee.
Preparing the site
- Let building users know which areas are affected
- For older buildings, check the asbestos register before work
- Send any specification or drawings in advance

Advice
How the job changes by surface
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area and damaged joints are redone rather than patched.
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. One applicator team gives the same finish everywhere.
When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Oversized gaps that need packing or adjustment by others
- Damage to finishes by other trades after we have sealed
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly.
What we seal
- Window and door perimeters
- Internal decorators’ caulk

Your questions answered
Do you take on work at healthcare sites like St John's Rooms And Chapel?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Do you cover business parks and estates near Baybridge, such as Wessex Business Park?
Yes. Estates, retail parks and business parks around Baybridge, Wessex Business Park among them, are all within reach. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Can you fit around our programme?
We follow the trades through the building. Areas are sealed as they’re released by the site team, and we will raise anything that holds the work up.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Do you use the sealant named in the specification?
Specification first, then the maker’s instructions. Preparation, backing and depth follow the product guidance.
Can fire-rated sealing at service penetrations be included?
It can be part of the package where specified. Tell us what records you need and we’ll confirm with the quote.
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Share drawings and the specification as soon as possible
- Use the product the specification names
- Keep finished joints away from paint, plaster and scrapers
- Keep scrapers and abrasive pads off new beads
A new structure shifts as it loses construction moisture. The right product in each joint copes with that, but caulk in a joint that moves more than expected may crack. We can advise if a joint needs a different product.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Water gets behind trays, vanity tops and panels, leaving the remedial work to the contractor. Getting the product and preparation right first time avoids that.
Building and refurbishing in Baybridge
Central London is about 61 miles from Baybridge. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. Baybridge sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.
For contractors at a school such as Owslebury Primary School, sealing has to be finished before term starts. Hospital estates such as St John's Rooms And Chapel (4.7 miles north-west of Baybridge) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Units on estates such as Wessex Business Park, 2.7 miles to the west of Baybridge, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
