About our facade sealing in Lower Rainham
We don’t install glazing systems or replace glass. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters. If you have new sealant peeling off old mastic and leaks at window and door perimeters, we can help, whatever the surface. Searching for sealant specialists in Lower Rainham? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Around smaller places like Lower Rainham, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Sites and facades in and around Lower Rainham
Lower Rainham sits close to the coast, within about 1 mile. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Lower Rainham sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.
Projects at schools like Thames View Primary School work to term dates, so mastic is programmed tightly. Hospital estates such as Medway Maritime Hospital (to the west of Lower Rainham) 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.

Our process
Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. Smaller jobs around Lower Rainham can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- Failed beads are removed in full and the joint faces cleaned.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
Before we start on site
- Have the specification and drawings to hand
- Tell us which areas need to stay in use
- Flag any permit to work we’ll need
Quotes
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
Advice
Do you need facade sealing in Lower Rainham?
Overlaying old sealant is a common shortcut that fails quickly. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.
These are often picked up first by site or facilities staff:
- Previous reseals run over old sealant
- Weathered joints at frame-to-structure perimeters
- Cold air coming in at window perimeters
- Gaps between rainscreen or cladding panels
Building work at universities like University of Greenwich - Medway, 3.4 miles north-west of Lower Rainham, is often timed for the summer, mastic included.
Questions to ask before you book
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will failed sealant be removed rather than covered?
- Which product they’ll use, and why it suits the joint
- Their plan for phasing and protecting the area
Work for main contractors and building owners
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Lower Rainham can form part of a wider programme across Medway.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
What affects the price in Lower Rainham
A fixed quote reflects the actual work. It allows for:
- Removal of failed or old sealant
- Access and working height
- Whether the work must be split into stages
- Induction, permit and paperwork requirements
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 you’ll have a fixed figure to work with.
What to include in your enquiry
There’s no need for a formal survey. These details are enough to start:
- Access details, including height
- Whether the building will be occupied during the work
- The postcode of the building
- Specification clauses that apply
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or email drawings and photos.
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Joints too narrow for the movement they take, which need redesign
- Arranging specialist high-level access, which is planned with the client
- Replacing glass or failed glazing units
If you are not sure, just give us a call on 01277 525 020 or email the details over and we will give you a straight answer.
What we seal
- Stone and brick facade joints
- Shopfront frames
- Window and door perimeters
- Cladding panel joints
- Coping and flashing joints
- Perimeter joints where frames meet the structure
After the work
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Never let anyone seal over old sealant
- Ask about asbestos in pre-2000 mastic
- Walk the elevations once or twice a year
- Plan facade sealing alongside redecoration
Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.
Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail, rather than waiting for a ceiling stain.
