How we handle construction mastic in Ruxley
A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility and gives you a consistent finish across the job. If you’re dealing with oversized or tapered gaps around new frames and old sealant on a refurbishment that needs stripping before new work, we can put it right, on sanitary and kitchen joints, brick and block movement joints and window and door perimeters alike. A specialist sealant contractor works differently from a general builder: on jobs in Ruxley, preparation and product choice get the time they need.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Ruxley must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Looking after the joints
Once the work is signed off, a little attention goes a long way:
- Bring the mastic contractor in after the last trades are through
- Brief the final clean team to avoid blades near sealant
- Stick to the specified sealant rather than a generic substitute
- Don’t force external sealing on a damp or frosty day
Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby.
Snag items left to the last week put handover at risk. A planned close-out through each area as it completes keeps the list short and keeps handover on track.

Ruxley: questions and answers
Can you work on a hospital site such as Queen Mary's Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Do you take on jobs in Ruxley where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Can you clear a mastic snag list before handover?
Yes. We can work through a mastic snag list area by area before handover.
What happens if it’s left?
A quick bead over a damaged joint can get an area past inspection. Sealant can’t grip a contaminated or existing bead, and the defect comes back after handover. Damaged joints are removed and resealed from clean faces. In Ruxley, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Construction mastic in Ruxley: the local picture
Several hotels sit less than 2 miles from Ruxley. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Site traffic in Ruxley falls within London’s ULEZ, like everywhere else in Greater London. Deliveries are booked and storage is tight, so mastic materials come in as needed.
University estates such as University of Greenwich Avery Hill Campus (to the north-west of Ruxley) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. When a school such as Hope Community School is extended or refurbished, the mastic package is often squeezed into the holidays.

Signs you need construction mastic in Ruxley
On a live site, contamination is the biggest threat to a new joint. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond, so preparation matters as much here as on a reseal.
Typical triggers for a call:
- External joints sealed in damp or cold conditions that are now failing
- Inconsistent sealant finishes from plot to plot
- Window and door perimeters that won’t pass inspection
- Existing joints on a refurb that need cutting out and resealing
For a contractor working at a hospital such as Queen Mary's Hospital, 1.2 miles west of Ruxley, perimeter and facade sealing is planned around patients and deliveries.
What your quote should include
- What the guarantee covers, and for how long
- How the joint faces will be prepared and primed
- Which product they’ll use, and why it suits the joint
- Their approach to joint depth and backing
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a job in Ruxley, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised straight away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Preparing the site
- Send any specification or drawings in advance
- Share the asbestos register for older buildings
- Clear stock, furniture or equipment away from the joints

Advice
For managing agents and facilities managers
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Ruxley can form part of a wider programme.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
