Your local mastic man for Basingstoke
Basingstoke was rapidly developed in the late 1960s as an expanded town, part of the London overspill plan agreed between London County Council and Hampshire County Council. Office blocks, a ring road and a set of almost self-contained estates went up around the old market town, and those estates still house most of its people. Mr Mastic covers the whole town from our base in Crawley.
We reseal baths, showers, basins and worktops, replace window and door mastic and renew external joints on homes and commercial buildings. The method never changes: old sealant out, mould treated, joint dried, new bead in. If you have tried sealing over the old line, our guide on why sealant goes mouldy explains why the problem keeps coming back.
Expansion estates, Victorian streets and new neighbourhoods
The expansion estates include Lychpit, Chineham, Popley, Winklebury, Oakridge, Kempshott, Brighton Hill, Viables, South Ham, Black Dam and Hatch Warren. Most of these homes are now on their second or third bathroom, and we often find layers of old sealant, baths that have dropped a little, and uPVC windows with mastic that has hardened and split after decades of sun.
Older Basingstoke survives around the Top of Town, the historic heart, where the Willis Museum occupies the former Town Hall rebuilt in 1832. The council’s Basingstoke Town Centre, Fairfields, South View and Brookvale West conservation areas cover Victorian and Edwardian streets, and all four have Article 4 Directions, which mean planning permission is needed for work such as replacing windows. That makes looking after the existing frames, with sound mastic and a paintable sealant where needed, all the more worthwhile.
Newer growth came in Popley, Hatch Warren and Beggarwood in the mid to late 2000s, and builder sealant in those homes often fails as they settle. Our shower resealing page explains how we put it right.
Ring roads, flats and town-centre blocks
The Ringway, built in the 1960s, encircles the town centre, and the flats and apartment blocks around it bring the classic risk of a failed shower seal showing up on the ceiling below. We can work with managing agents on keys, access and parking, which near Festival Place and the station needs planning ahead.
Outside, many 1960s and 1970s homes have long runs of joints where windows, doors and panels meet brick. Hardened mastic there lets wind-driven rain behind the frame. We cut it out, fit backing rod where the gap is deep and use a flexible weatherproof sealant in a colour that suits the frame and brick.
Office parks, the hospital and the colleges
Basingstoke has a lot of office space, from the redeveloped Basing View to Chineham Business Park, and the M3 skirts the south-eastern edge of town with junctions 6, 7 and 8 close by. Festival Place, opened in 2002, is the main shopping centre. Queen Mary’s College and Basingstoke College of Technology serve the town, and North Hampshire Hospital is its main hospital. Staff washrooms, showers and kitchens in places like these need resealing from time to time, and our commercial sealant page explains how we work out of hours.
Landlords and letting agents book us between tenancies, and with so many homes of a similar age on the expansion estates, we can often quote for several properties together and reseal them on consecutive days.

Questions we’re asked in Basingstoke
Do you cover all of Basingstoke?
Yes. We cover the town centre and Top of Town, every estate from Brighton Hill to Chineham, Hatch Warren, Beggarwood, Rooksdown and Old Basing.
My house is in the Fairfields conservation area. Can you reseal the windows?
Yes. Resealing existing frames is routine. Article 4 Directions apply to changes such as replacing windows, so check with the council before any of that.
Our 1970s house has cracked mastic all round the windows. Can you redo it in one visit?
Usually, yes. We cut out the old mastic, clean the frames and brickwork, and apply a flexible weatherproof sealant.
Can you reseal staff facilities on a business park out of hours?
Out-of-hours working can be arranged for commercial jobs, so washrooms are ready for the next working day.
Our shower in Beggarwood is only a few years old and the sealant has split. Why?
Newer homes settle, and builder sealant often fails early. We remove it, prime and reseal.
Do you work for letting agents?
Yes. We reseal between tenancies and can quote for several properties together.
How long before I can use the bath?
Usually around 24 hours. We will confirm the cure time before we leave.
Is the work guaranteed?
Yes. Every job has our one-year guarantee.
