Mastic and sealant work in Redbourn

Sealant jobs we do in Redbourn

Redbourn has more than a hundred listed buildings in its conservation area and a good stock of post-war family houses around them, so the sealant work here ranges from fragile old cottages to busy family bathrooms. Mr Mastic covers Redbourn from our base in Crawley, along with Harpenden, St Albans and Hemel Hempstead nearby.

We reseal baths, showers, sinks and worktops, replace failed window and door mastic and seal external joints. Each job starts with the old sealant cut out and the joint cleaned and dried. If you’re weighing up who to call, our guide to choosing a mastic man lists the questions worth asking.

Church End, the Common and the High Street

Redbourn’s conservation area was first designated in 1969 and extended in 2001. It has three parts with their own feel. The High Street follows the straight line of Roman Watling Street, with two-storey buildings close to the pavement, a reminder of the coaching days when the village had dozens of inns. Around the Common the layout is looser, with timber-framed cottages, Georgian brick houses, nineteenth-century terraces and even a few thatched roofs. Church End has a quieter, older character around St Mary’s Church. Red brick, render and clay tile are the usual materials, and timber sashes and casements are typical.

Outside the conservation area, The Park is mostly 1960s terraces in the Span style, with mono-pitch or flat roofs and shared gardens, and most of the post-war expansion lies north of the Common: detached and semi-detached houses and bungalows around Snatchup, Crouch Hall Lane and Flamsteadbury Lane, with more spacious newer homes at Bettespol Meadows.

That gives us old timber frames and uneven walls in the centre, and in the newer streets the everyday jobs of failing bath seals, shrinking kitchen joints and hardened mastic around replacement windows.

Cottages, Span terraces and what they need

In the timber-framed and thatched cottages, small bathrooms are often tucked under the roof or into a lean-to, and the building moves a little all the time. We use a flexible sealant and keep the bead neat, and around painted timber windows we can use a paintable product. Inside a listed building, resealing is routine maintenance, but outside we keep to like-for-like work.

The 1960s terraces at The Park have big windows and panels set into simple frames, and the joints around them have often been patched over the decades. Cutting those out and replacing them with a modern, flexible, weatherproof sealant makes a real difference to draughts and damp. Our external joint sealing page covers this work.

Pubs, care homes and the village’s businesses

Redbourn still has a good number of pubs and restaurants, and their kitchens and customer toilets work hard. We can reseal before opening or after closing. St Matthew’s and Gertrude Peak Place are among the village’s care homes, and settings like those need anti-bacterial, anti-fungal sanitary sealants laid neatly enough to clean easily.

The industrial units on the former jam factory site off the High Street and the businesses in East Redbourn have staff facilities too. We also work for landlords and letting agents, resealing between tenancies.

Questions we’re asked in Redbourn

Do you cover all of Redbourn?

Yes. We cover the whole village, including the High Street, the Common, Church End, The Park and the newer streets to the north, plus Harpenden, St Albans and Hemel Hempstead.

Can you reseal a bathroom in a listed cottage?

Yes. Indoor resealing is ordinary maintenance. We use flexible sealants that suit old, moving buildings and keep the finish neat.

The window joints on my 1960s house at The Park are draughty. Can you help?

Yes. We cut out the old, patched sealant and replace it with a flexible, weatherproof one, using backing rod where the gap is deep.

Do you work in care homes?

Yes. We use hygienic sanitary sealants and work room by room so residents are disturbed as little as possible.

Why is the sealant on the Common cottages so uneven?

Old timber-framed walls are rarely straight, so joints vary in width. We size each one and use backing rod where a gap is deep, so the bead stays neat.

Can you reseal a pub kitchen without closing?

Out-of-hours working can be arranged for commercial jobs, so the kitchen can be done before service or after closing.

How long does a bath reseal take?

Usually a couple of hours, plus curing time. We’ll tell you when it’s safe to use before we leave.

Is the work guaranteed?

Yes. Every job comes with our one-year guarantee.
