About our mastic sealing in Watch House Green
For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card and we hold public liability insurance. Resealed mastic joints in Watch House Green carry our 12-month guarantee. If you have a mix of products and colours from past repairs and draughts at frames across a block, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Watch House Green, preparation and product choice get the time they need.
Owners and agents with buildings around smaller places such as Watch House Green tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Leave it or put it right?
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows and occupiers notice. Halls, stores and units around places like Watch House Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Looking after buildings in and around Watch House Green
At about 34 miles from central London, Watch House Green is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. Rainfall across the South East, Watch House Green included, is lower than in many parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
If your remit includes a building such as Felsted Primary School, frame and door mastic can be programmed for the holidays. If you own or manage units on a site such as Concord Farm Business Centre, 2 miles east of Watch House Green, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. If you are responsible for a building such as Church of the Holy Cross, frame and door mastic needs the same attention as any other property.

Advice
Cost factors for mastic joints
Quotes vary with the job. Expect it to depend on:
- Travel to remote or island sites
- The site’s rules and procedures
- How much there is to seal
- Any access equipment needed
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote when you’re ready.
What we need to price the job
There’s no need for a formal survey. A few details are enough to get going:
- Any dates the work must fit around
- A wide shot and a close-up of the area
- How the joints are reached, and at what height
- The site address and postcode
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or use the quote form.
After the work
To get the most from the new sealant:
- Make mastic part of routine maintenance checks
- Prioritise elevations facing the weather
- Log resealing dates block by block
- Make it easy for occupiers to report draughts
Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.
Your questions answered
Does your area include sites such as Concord Farm Business Centre, near Watch House Green?
Yes. Our area takes in Watch House Green and its surroundings, with estates and business parks such as Concord Farm Business Centre included. To start, just call 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Is Watch House Green off your patch?
Not at all. Watch House Green is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
What do you charge?
Every job gets its own fixed quote. To get one, call 01277 525 020 or email drawings and photos with a description of the work.
How many days will you need on site?
That varies with the scale of the job, but the work usually takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Leaks from above rather than through a joint
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Leaks through the frame itself rather than the perimeter
If you are not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
Surfaces we seal
- External wall and movement joints
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Shopfronts below residential blocks
- Balcony and threshold joints
Different surfaces, different methods
Tenement and older buildings
Traditional buildings have joints that need a careful approach. We look at the substrate before choosing a sealant.
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Tidy, sound joints keep them looking cared for.
