Mastic sealing for Baybridge sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- Leaks through the frame itself rather than the perimeter
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
If you’re not sure, just speak to us on 01277 525 020 or email us and we’ll give you a straight answer.
Surfaces we seal
- External wall and movement joints

Mastic sealing in Baybridge
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. We work on balcony and threshold joints, communal entrances and stairwells and shopfronts below residential blocks, and what we are called in for most is failed external movement joints and damp patches beside frames. One point of contact handles commercial sealant work in Baybridge from the first photographs to the final walk-round, whether it’s one building or several.
For buildings around smaller places like Baybridge, we group work so one trip covers it. Photos of each elevation help us quote accurately.
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’re clear about what is covered before work starts.

Why deal with it now?
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows and occupiers notice. For buildings around smaller places like Baybridge, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Mastic sealing in Baybridge: the local picture
Baybridge is about 61 miles from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
For owners of several units at places like Wessex Business Park (2.7 miles west of Baybridge), one programme can deal with frame and external mastic across the lot. For agents with blocks near Shawford station, 3.5 miles west of Baybridge, a block-wide mastic programme deals with frames, balconies and entrances in one go. Older community buildings, Church of St Andrew among them, often have frames of mixed ages whose mastic varies.

Our process
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For work around Baybridge, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- 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
- Explain the parking and delivery arrangements
- Send asbestos survey details if the building is pre-2000
- Send any specification or drawings in advance

Baybridge: questions and answers
We manage a building near Shawford station. Can you help?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
Is Baybridge off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn so you can plan around it.
General trades versus a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
