About our construction mastic in Epping
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old, and on older buildings we ask for the asbestos survey before disturbing anything. After that, the joints are prepared and sealed to the specification. We work on cladding and panel joints, sanitary and kitchen joints and window and door perimeters, and the failures we’re asked to look at most are bath and shower joints scraped during the final clean and existing joints on a refurb that need cutting out and resealing. Whether you call it commercial sealant work, mastic application or joint sealing, in Epping it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around places like Epping, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Different surfaces, different methods
Window and door perimeters
Internal perimeters are typically sealed with a paintable product where decorating follows. We follow what’s specified, and colour-matched products can be used where the frame is on show.
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s for gaps that stay still and get painted while moving joints need a flexible sealant.
What we are called out for in Epping
Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated.
Things that normally lead to an enquiry:
- Cracks opening in caulked internal joints
- Oversized or tapered gaps around new frames
- Snag items on joints that need redoing before handover
- Inconsistent sealant finishes from plot to plot
Historic houses such as Hill Hall, 2.5 miles south-east of Epping, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
What your quote should include
- What level of public liability insurance do they hold?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Who will actually carry out the work
- How long is the guarantee, and what does it include?
Sites and facades in and around Epping
The area within 2 miles of Epping holds a number of hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. Epping sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.
Extensions at sites like Saint Margaret's Hospital (0.6 miles north-east of Epping) typically sit beside working departments, and the mastic follows strict access rules. Work at a hotel such as Cock Hotel, under half a mile to the north-east of Epping, tends to be programmed around bookings, mastic included.
Epping is about 4 miles north-east of Loughton, in Essex. Anywhere in CM16, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 644 places in Essex, large and small. London is covered too, some 16 miles away.
Anyone looking for construction mastic in CM16 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. If your site is on High Street, Station Road and Twankhams Alley or close by, send details and we will quote for mastic packages. Main routes into Epping include the B181 and B182, which helps when planning parking and deliveries for the job. Just outside Epping, we also work in Ivy Chimneys (1 mile south-west), Steward's Green (1 mile south-east), Fiddlers Hamlet (1 mile south-east), Theydon Garnon (2 miles south) and Hobbs Cross (2 miles south-east). Nearby towns on our patch include Harlow (5 miles north), Brentwood (10 miles south-east), Billericay (14 miles east), Loughton (4 miles south-west), Waltham Abbey (4 miles west) and Stansted Mountfitchet (15 miles north).
Local landmarks in Epping
We work on buildings around St John's Church of England Voluntary Controlled School, Thornwood Common Flood Meadow and The Black Lion pub, among other places. Well-known places in the area include Epping Signalling Museum (under half a mile south) and St. Margaret's Hospital (0.7 miles north-east). Not far away are Gernon Bushes.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. If neighbouring businesses or buildings around Epping need work too, visits can be combined. Tell us your site hours and we will plan around them.
- First we take quantities off the drawings and read through the specification.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Every joint is prepared, set to depth and sealed with the specified product.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Preparing the site
- Tell us which areas need to stay in use
- Let us know about inductions and permits
- Point out parking and an unloading spot

What happens if it’s left?
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple and a consistent finish. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
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.
Why us?
- A fixed quote before work starts
- Colours chosen to suit frames, cladding or finishes where possible
- Joints cleaned back to sound surfaces
- Commercial sealant work since 2005

Questions we’re asked in Epping
Is a smaller place like Epping outside your area?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Is a hospital such as Saint Margaret's Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you work to our specification?
We follow the specified sealant, and we’ll raise it if something in it doesn’t suit the joint. Specifications often reference BS EN 15651 or BS 6213.
How do you work with the site programme?
We work to your programme. Tell us the sequence and we’ll plan applicators around it so sealing follows the trades.
Are you CHAS accredited?
We’re CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. We confirm any paperwork you need with the quote.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Share drawings and the specification as soon as possible
- Allow flexibility for external sealing in damp or cold weather
- Release areas for mastic once other trades have finished in them
- Brief following trades on areas that have been sealed
Record which products went where in the handover file. Future maintenance is easier when the products are known, and tells you what to reseal with. We can confirm the handover information you need when we quote.
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 avoids a rush.

When something else is needed
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Designing joint widths or choosing the specification (that sits with the designer)
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Faulty frames rather than failed sealant
If in doubt, phone 01277 525 020 or send details through our quote form and we’ll say what we think.
