Mastic sealing for commercial buildings in Lower Sheering
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. We work on window and door perimeters on blocks, communal entrances and stairwells and external wall and movement joints, and what we’re called in for most is window mastic that has split and shrunk and open joints in brickwork or panels. Most enquiries from Lower Sheering start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Lower Sheering, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
A 12-month guarantee applies to all our work in Essex. If an installation problem shows up, give us a call on 01277 525 020 or use the quote form and we’ll arrange a return visit.

Block-wide mastic in Lower Sheering
Rainfall across the South East, Lower Sheering included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. At about 24 miles from central London, Lower Sheering is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property.
Buildings close to stations like Sawbridgeworth station, under half a mile to the north of Lower Sheering, are often flats over shops, with frame mastic to keep sound. With historic buildings such as Barrington Hall, 4.2 miles north-east of Lower Sheering, in the wider area, owners of older properties around Lower Sheering should expect mastic to need a product that suits old masonry.
Lower Sheering is about 3 miles north-east of Harlow, in Essex. We send applicators to Lower Sheering for mastic joints, handled exactly as we handle every other area. Lower Sheering is one of 644 places in Essex on our list. Sites around London have their own page, about 24 miles away.

On site: what to expect
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off.

- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.

Advice
Should maintenance staff do it?
Certain joints really need a specialist: 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.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Common problems we fix in Lower Sheering
Poor preparation explains many failed joints. Without clean, sound faces and a primer where the product needs one it comes away from one face.
It’s worth sending us details if you spot any of the following:
- Damp patches beside frames
- Patchy repairs in mismatched sealant
- Draught complaints from residents or tenants
- Brittle perimeter mastic across a building
If your remit includes a building such as Fawbert and Barnard Infants' School, frame and door mastic can be programmed for the holidays.

What sets the cost
A fixed quote reflects the actual work. It takes account of:
- Phasing around occupants
- Induction, permit and paperwork requirements
- How much there is to seal
- Travel to remote or island sites
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Before you send an enquiry
Good information means a firmer quote. Helpful details to send:
- When you need the work done
- Whether the building will be occupied during the work
- The product your specification calls for
- The postcode of the building

Do you cover business parks and estates near Lower Sheering, such as Allen House Business Centre?
Yes, sites like Allen House Business Centre are within our area, along with the rest of Lower Sheering. A few photographs and the unit address let us price the work.
Is Lower Sheering too small for you to travel to?

Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
Can you reseal a whole block or estate?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
Do you work with property factors and landlords?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Why deal with it now?
Looking at mastic during planned maintenance costs little. Leaving it until there’s a leak turns it into reactive work and less choice about when. Converted and older buildings near places like Lower Sheering tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Masonry that has broken away beside the joint
- Leaks from above rather than through a joint
- Failed window or door frames, which need a window contractor
