Mastic and sealant work in Fareham

Sealant jobs we do in Fareham

Fareham sits at the north-west tip of Portsmouth Harbour, where the creek once powered the Bishop of Winchester’s mills. By the 1970s the town had grown to take in Portchester, Titchfield, Catisfield and Funtley, and today the borough also covers Stubbington, Hill Head, Sarisbury and Warsash. Mr Mastic travels in from our base in Crawley to work across all of it.

We reseal baths, showers and kitchens, replace window and door mastic and renew external joints. Nothing goes on top of old sealant: we strip it out, treat the mould, clean and dry the joint and then lay a new bead. Our silicone removal page explains why that first step decides how long the new seal will last.

Georgian frontages, post-war growth and Welborne ahead

Fareham High Street is known for its historic Georgian buildings and is one of 13 conservation areas in the borough, alongside Osborn Road, Wallington, Town Quay, Titchfield, Castle Street in Portchester, Warsash and others. Period buildings here often have timber sashes, render or painted brick, and the joint between frame and wall may need a sealant that can be painted rather than silicone. In conservation areas it is worth checking with the council before changing anything visible from the street.

Most of Fareham’s homes are newer. The town saw major residential development in the 1960s, and those houses and bungalows have usually been through more than one bathroom refit, leaving layers of tired sealant and uPVC window mastic that has hardened in the sun. Whiteley, developed from the late 1990s north of the M27, is mainly residential and its homes are now at the age when original sealant gives out.

Looking ahead, Welborne is planned north of the M27 with around 6,000 homes. New builds of every size need sealant checked after the first year, and our new build mastic service covers that.

Harbour air and waterfront villages

Much of the borough lies along the water, from Portsmouth Harbour and Fareham Creek to the shore at Hill Head and Warsash. Homes facing the harbour or the Solent take wind-driven rain and salt-laden air, and external mastic on south and west faces dries out and cracks sooner than it would inland. We use durable, weatherproof sealants set at the right depth with backing rod, and we check sills and the joints beneath them as well as the frame edges.

In flats near the town centre and newer blocks, a failed shower seal usually shows first in the flat below. We can arrange access, keys and parking with managing agents before we arrive.

Business parks, offices and the town centre

Solent Business Park at Whiteley is extensive, and Cams Hall, a Palladian mansion restored for office use in 1995, sits on an estate that now includes a technology park. In the centre, Fareham Shopping Centre, Fareham College and the reopened Fareham Live venue all have washrooms and kitchens that get heavy use. We can work out of hours on commercial jobs, and our commercial sealant page explains the approach.

Landlords and letting agents across the borough book us between tenancies.

Fareham: common questions

Do you cover all of Fareham?

Yes. We cover the town centre and High Street, Portchester, Titchfield, Stubbington, Hill Head, Sarisbury, Warsash and Whiteley.

My house is on the High Street in a conservation area. Can you reseal the windows?

Yes. We can use a paintable sealant where needed. Check with the council before changing anything visible from the street.

Why does the mastic on my harbour-facing windows fail so quickly?

Sun, wind and salty air dry out and stress external sealant. Cutting out the old mastic and using a flexible weatherproof product gives a longer-lasting joint.

We bought a home in Whiteley in the early 2000s. Is the sealant due?

Very likely. Bathroom and window sealant of that age is often hard and cracked. We can check it and reseal where needed.

Can you work at an office on Solent Business Park out of hours?

Out-of-hours working can be arranged for commercial jobs, so washrooms and kitchens are back in use for the next working day.

Do you work for letting agents?

Yes. We reseal between tenancies and can quote for several properties together.

I live in a 1960s bungalow in Fareham. Is resealing the bath straightforward?

Usually, yes. We often find several old layers of sealant in homes of that age, so we strip them all before laying one clean new bead.

How long does a bathroom reseal take?

Most baths or showers take a few hours, including removing the old sealant, then around 24 hours to cure.
