Your questions answered
Will you plan work around the academic year at somewhere like Writtle University College Cow Watering Campus?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is a hospital such as Brentwood Community Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Do you do fire-rated sealing on new builds?
Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. Fire-stopping design and sign-off sit with the designer and building control.
Can the building stay open while you work?
Yes, with some planning. Tell us your site hours and access windows and we will plan around them.
What does a mastic package typically include?
The scope comes from the specification and drawings, but frames, sanitary, kitchens, caulk where specified and snagging are typical.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a quote.
Construction mastic in Green Street, done properly
Buyers, tenants and clients notice sealant lines long before they notice the structure. Untidy or missed joints are among the commonest snag items and clearing them late eats into the handover window. We seal so the snag list stays short, whatever the size of the scheme. The enquiries we see most involve bath and shower joints scraped during the final clean and early adhesion failures on new external joints, across internal decorators’ caulk, window and door perimeters and sanitary and kitchen joints. Facilities teams, main contractors and managing agents in Green Street tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Construction in and around smaller places such as Green Street is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Our workmanship is guaranteed for 12 months, in Green Street as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Cost factors for mastic packages
A fixed quote reflects the actual work. It takes account of:
- Joint width, depth and condition
- How accessible the joints are
- Phasing around occupants
- Quantities, in metres or numbers
Pricing mastic packages depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- The site address and postcode
- Any specification or named product
- Access details, including height
- A wide shot and a close-up of the area
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
Mastic packages on Green Street sites
Green Street is about 23 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. Rainfall across the South East, Green Street included, is lower than in many parts of the UK. 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.
New wings at hospitals like Brentwood Community Hospital, 3.8 miles to the south-west of Green Street, bring long runs of window and panel joints to seal. For contractors at a school such as Ingatestone Infant School, sealing has to be finished before term starts. Building work at universities like Writtle University College Cow Watering Campus (to the north-east of Green Street) is often timed for the summer, mastic included.
Green Street is about 4 miles north-east of Brentwood, in Essex. Across the CM4 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Essex, 644 places are covered, including Green Street. Sites around London have their own page, about 23 miles away.

What the job involves on each surface
Kitchens and utility areas
Kitchen joints are sealed after fitting and before final clean. The sealant is a kitchen-grade product, food-safe where food contact is possible.
Fire-rated sealant where specified
Fire-rated sealant is one type of fire-stopping product. Other products are used for some services and gaps. Tell us what records you need and we will confirm with the quote.
Looking after the joints
To get the most from the new sealant:
- Plan external elevations with the weather in mind
- Ask installers to correct oversized gaps first
- Keep product details for future maintenance
- Stick to the specified sealant rather than a generic substitute
At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later and avoids guesswork when joints are renewed. Tell us what records you need and we’ll confirm with the quote.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure. We flag them as soon as we see them.
How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes whatever the programme allows, since the work follows the trades as areas are released, and we clear our waste as we work. Rural sites near Green Street may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Joints are prepared, backed and sealed to the specification.
- Snags are cleared and the package signed off with our 12-month guarantee.
Getting the site ready
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints
- Send any specification or drawings in advance
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

If in doubt, call 01277 525 020 or email us and we’ll say what we think before you book.

- Internal decorators’ caulk

- Brick and block movement joints
Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
