Resealing and mastic work across Harlow
Harlow is one of Britain’s post-war new towns, built neighbourhood by neighbourhood, so a single street can tell you a lot about the bathrooms, kitchens and windows behind its front doors. Mr Mastic covers Harlow from our base in Crawley, a straightforward drive round the M25, for homeowners, tenants, landlords and businesses.
If water is getting past a shower seal or the bead around your bath has split, it is worth dealing with sooner rather than later. Damp behind tiles and under floors spreads quietly. Our article on leaking shower sealant explains the warning signs, and when we visit we remove the failed seal completely and reseal with anti-fungal silicone.
A planned town in layers
Harlow was designated a new town in 1947, with a master plan by Sir Frederick Gibberd. Mark Hall was the first new neighbourhood and is now a conservation area, while older settlements such as Old Harlow, Potter Street, Great Parndon, Latton, Tye Green and Netteswell were taken into the town. There are terraces, maisonettes and low-rise flats of the 1950s and 1960s throughout, and many have been modernised with new bathrooms and uPVC windows. Where a refit was done quickly, we find sealant laid over sealant or gaps filled with too thin a bead.
The town kept growing. Sumners and Katherines were built in the 1970s, Church Langley was completed in 2005, and Newhall, on the eastern edge, has contemporary homes including the Newhall Be scheme by Alison Brooks Architects. Newer homes often lose their first sealant within a couple of years as timber dries and the building settles.
Harlow also has a high share of social housing and some offices converted into small flats under permitted development, so a lot of homes are managed by councils, housing associations and landlords. In those homes, resealing is often done between tenancies or after a tenant reports mould, and a tidy, lasting job saves repeat visits.
Tower flats, maisonettes and managed blocks
The Lawn, completed in 1951 and now Grade II listed, is described as the first residential tower block in the UK, and Harlow has many more blocks of flats and maisonettes. In stacked homes, a failed bath or shower seal can reach the ceiling below quickly, so repairs are often urgent. We can arrange access through the managing agent or housing provider, book parking and keep shared areas clean. In maisonettes, where the bathroom is often upstairs over the living room, a sound seal around the bath protects the ceiling and decoration below.
In converted office buildings and modern blocks, sealant is also part of how the building behaves in a fire. Where gaps around service pipes or doors need it, our fire-rated sealant work uses the right tested product for the job.
Enterprise zone, hospital and the town centre
Templefields and The Pinnacles were Harlow’s planned industrial areas, and the Enterprise Zone created in 2011 includes Templefields and the London Road business parks. Offices, labs and warehouses there all have kitchens, washrooms and showers that need regular resealing. We can work out of hours to suit.
Princess Alexandra Hospital is in Harlow, and the care homes, surgeries and clinics around it need sealant that is hygienic and easy to clean. Harlow College, schools and town centre shops are also places where we can take on remedial sealant work when joints have failed.

Jobs we take on in Harlow
- Bathroom & kitchen resealing: Mouldy or split sealant around baths, shower trays, basins and sinks removed completely and replaced with a neat, hygienic bead.
- Window & door mastic: Hardened, gappy mastic around frames, sills and French or patio doors cut out and renewed to keep draughts and rain out.

Your questions about mastic work in Harlow
Do you cover all of Harlow?
Yes. We cover Old Harlow, Mark Hall, Potter Street, Great Parndon, Latton, Tye Green, Netteswell, Church Langley and Newhall, and nearby villages such as Churchgate Street.
My shower is leaking into the flat below. Can you come quickly?
Call us and we’ll arrange the earliest visit we can. In the meantime, stop using the shower to limit the damage.
Can you work with my housing association or managing agent?
Yes. We can arrange access, parking and timings with the agent or housing provider.
My Newhall house is only a few years old and the sealant is splitting. Why?
New homes settle and dry out, which pulls at the first sealant. We remove it and reseal with a flexible, anti-fungal silicone.
Do you fit fire-rated sealant?
Yes. We use tested fire-rated products where the job calls for them and can explain what we used.
Can you work in offices on the business parks out of hours?
Yes, out-of-hours working can be arranged for commercial jobs.
Can you reseal a bath in one of the older new town houses that has dropped away from the tiles?
Yes. We cut out the old sealant, pack the gap where it is deep and lay a new bead wide enough to cope with small movements of the bath.
Is it worth resealing before I sell or let my Harlow flat?
Clean, white sealant makes a bathroom look cared for and helps prevent damp, so many owners and landlords do it before viewings.
