Common questions from Navestock Common clients
Is a hospital such as Suttons Manor Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Could you schedule work at a campus like Havering Technical College for the vacation?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Can staff carry on working while you are here?
In the majority of cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Do you do internal caulk as well as external mastic?
Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens in one fixed quote.
Does weather affect external mastic work?
External mastic depends on conditions: the joint needs to be dry and within the product’s temperature range. We plan external elevations with that in mind.
Is Navestock Common in your area?
Yes. We cover Navestock Common, and you can call 01277 525 020 or email drawings and photos to get started.
Construction mastic in Navestock Common
We work to the specification and the programme. Where the specification names a product, we use it; any alternative we suggest is put to you before anything changes. Backing, primer and depth follow what the sealant maker sets out. We work on sanitary and kitchen joints, internal decorators’ caulk and floor and skirting junctions, and the usual reasons a site gets in touch are perimeter gaps outside the sealant’s range and snag items on joints that need redoing before handover. A specialist sealant contractor works differently from a general builder: in Navestock Common, that means joint design, primers and backing rod as standard.
Construction in and around smaller places such as Navestock Common is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
A 12-month guarantee applies to all our work in Essex. Should something we installed fail, phone 01277 525 020 or email a schedule or drawings and we’ll come back to it.

Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. Rural sites near Navestock Common may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- Drawings, the sealant specification and your programme come to us for pricing.
- A fixed quote sets out the scope, the products and the sequence.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- We close out snagging and hand over with a 12-month guarantee.
What we need from you
- Send any specification or drawings in advance
- Tell us which areas need to stay in use
- Flag any permit to work we will need

General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

What else we do in Navestock Common
When to call us in Navestock Common
A new building moves while it dries and settles. Materials lose construction moisture and shrink, which opens up internal joints, particularly where caulk has been used in a joint that moves. Picking a flexible sealant where there’s movement keeps snags down.
Any of the following is a good reason to get the joints checked over:
- Window and door perimeters that won’t pass inspection
- Cracks opening in caulked internal joints
- External joints sealed in damp or cold conditions that are now failing
- Bath and shower joints scraped during the final clean
For contractors at a college like Havering Technical College, 1.7 miles south-east of Navestock Common, perimeters and internal sealant are timed for the holidays.
Before you book anyone
- How they handle RAMS and site documents
- Their approach to joint depth and backing
- What the guarantee covers, and for how long
- Whether old or failed sealant will be cut out, not overlaid
After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Keep product details for future maintenance
- Ask cleaners to use soft cloths around fresh sealant
- Don’t schedule sealing before decorators and flooring are done
- Don’t force external sealing on a damp or frosty day
Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean, so stick to soft cloths and gentle cleaners near sealant.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks so external sequencing builds in some flexibility.
Contractors’ notes for Navestock Common
Navestock Common is about 16 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. Navestock Common sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.
Hospital estates such as Suttons Manor Hospital, 2.2 miles to the north-west of Navestock Common, 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. For contractors at a school such as Drapers' Academy, sealing has to be finished before term starts.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
What sets the cost
Before we quote, we look at:
- The product specified
- Phasing around occupants
- Whether old sealant has to be cut out first
- How much there is to seal
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
Details that help us quote
Good information means a firmer quote. When you get in touch, include:
- A wide shot and a close-up of the area
- Your programme or deadline
- Specification clauses that apply
- Rough lengths or quantities, or drawings if you have them
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
