London’s northern edge, just off the M25
Enfield is the first London borough we reach coming down from Bedford, which makes it one of the easiest places for us to work.
Along the Lea Valley, Brimsdown, Ponders End and Enfield Lock are lined with warehouses, trade counters and distribution sheds. Their floor joints, cladding laps, door frames and loading-bay details need industrial sealant, often polyurethane or polysulphide that can cope with forklifts, washdowns and temperature swings.
West of the A10 the borough changes completely. Enfield Town, Bush Hill Park, Winchmore Hill, Palmers Green and Southgate are full of Edwardian and inter-war houses, plus newer blocks of flats, and that is where our window and door mastic, shower resealing and kitchen sealant work comes from.
Meridian Water in Edmonton is one of the biggest regeneration schemes in London, and new apartment blocks there and around Enfield Town station bring plot mastic, cladding joints and internal silicone packages for contractors.

Sealant for Lea Valley warehouses and trade units
Failed floor joints break up under pallet trucks, and failed cladding sealant lets water into stock. On Enfield’s industrial estates we cut out the damaged joints, clean and prime the arrises and reseal with a sealant chosen for the traffic and exposure.
We can work out of hours or in phases so a unit keeps trading, and we provide RAMS and insurance documents before we start.

Windows, bathrooms and kitchens in Enfield homes
In the residential parts of Enfield the calls are usually about a leaking shower tray, a bath edge that has gone black, or windows where the mastic has cracked and let the draught in.
We take out the old sealant, prepare the joint properly and reseal it with the right product, whether that is a sanitary silicone in the bathroom or a flexible low-modulus mastic outside.
We are also a sealant specialist for façade, concrete and expansion joints, use non-staining sealant on stone and listed buildings like the brickwork around Forty Hall, and re-mastic blocks for managing agents. Homeowners call us for window mastic in Enfield on uPVC frames, bathroom resealing in Enfield, including wet room and en-suite joints, and shower resealing in Enfield.

Enfield sealant questions
Can you reseal warehouse floor joints without closing the unit?
Usually. We work in sections, out of hours if needed, and use sealants that cure quickly enough for traffic to return on a planned schedule.
How much does a mastic man cost in Enfield?
Domestic jobs are priced from photos; industrial jobs from joint lengths, access and downtime limits. Either way you get a written figure before we start.
How quickly can you get to Enfield?
Enfield is the closest London borough to our Bedford base, about an hour away, so we can often fit in small jobs within a few days.
Do you cover Edmonton, Southgate and Palmers Green?
Yes, the whole borough: EN1, EN2, EN3, N9, N13, N14, N18 and N21.
