Resealing and mastic work across Cookham

Cookham is really three places: Cookham Village, with a High Street that has changed little over the centuries; Cookham Rise, which grew up around the railway station on the Marlow branch line; and Cookham Dean, the most rural part of the parish and its highest point. Mr Mastic covers all three from our base in Crawley.

Most of our work here is in bathrooms and kitchens, and around windows and doors. We take out the old sealant completely, treat any mould and let the joint dry before a single new bead goes on. In older houses that care matters even more, because the surfaces either side of a joint are rarely straight. For the outside of the house, our window mastic guide explains how we choose the right product for each frame.

Old timber frames, station-era homes and the river

Cookham Village holds some of the oldest buildings in the area. Holy Trinity church is Grade II* listed, with a Lady Chapel from the late twelfth century, and Churchgate House nearby is timber-framed. Houses of this age move with the seasons, so a stiff, old bead around a bath or window will crack. We use flexible sanitary silicone inside and fill a bath before sealing it, so the bead is laid with the bath at its heaviest.

Cookham Rise is the newer middle of the parish, shaped by the arrival of the railway, and its houses have usually had bathrooms and kitchens refitted at least once. Typical jobs are worn shower tray joints, kitchen worktops where the sealant has shrunk back, and uPVC windows with mastic that has blackened and split.

Up in Cookham Dean the setting is more open, with commons and Bisham Woods on the western edge. Higher, more open ground means wind-driven rain on exposed walls, which is a good test of every external joint.

Working on the Thames side of the parish

The River Thames flows past Cookham between Marlow and Taplow, with Cookham Lock on Sashes Island and long moorings above Cookham Bridge. Homes close to the river and its tributaries, the Lulle Brook and White Brook, live with damp air for much of the year, which slows drying and encourages mould on bathroom sealant and external joints. We choose anti-fungal silicone indoors and check that outside joints are fully bonded, not just looking intact.

On the High Street, parking can be tight, so we agree arrival times and keep the van visit short. In older buildings divided into flats, we can speak to the owner or agent about access first.

Pubs, hotels and conference venues

The High Street has a selection of restaurants and pubs, and there are more in Cookham Dean, where The Sanctum on The Green is a hotel and inn. Larger venues include the John Lewis Partnership’s hotel and conference centre at Odney and Moor Hall, home of the Chartered Institute of Marketing. Guest bathrooms and staff facilities in places like these need resealing more often than a family bathroom, and we can work room by room. Our hotel sealant page explains how.

We also reseal for landlords with rented homes in the parish.

How it works

  1. Call or email. Tell us what needs doing, where it is and anything about access. Photos by email help.
  2. Quote and booking. We quote clearly before anything starts and fix a day that works for you.
  3. Strip back the old joint. Every bit of old sealant is removed and the joint is cleaned, treated for mould and dried.
  4. Neat new sealant. Each joint gets the sealant that suits it, laid and smoothed to a tidy finish.
  5. Cure and guarantee. We tell you when it can be used, and every job has our one-year guarantee.

Questions we’re asked in Cookham

Do you cover all of Cookham?

Yes. We cover Cookham Village, Cookham Rise and Cookham Dean, plus nearby Maidenhead, Furze Platt, Pinkneys Green and Bourne End.

Can you reseal a bath in a timber-framed house?

Yes. We use flexible sanitary silicone and fill the bath before sealing, so the bead copes with movement in the floor and walls.

My house is near the river and the bathroom sealant keeps going mouldy. Can you help?

Yes. We remove the old sealant, treat the mould and reseal with an anti-fungal silicone. Good ventilation and drying the bead after use help it last.

Can you work at a pub or hotel without closing rooms?

Yes. We work room by room, and out-of-hours working can be arranged for commercial jobs.

Parking on the High Street is difficult. Is that a problem?

No. We agree a time with you and keep the van visit short, carrying everything in ourselves.

Do you replace mastic around timber windows as well as uPVC?

Yes. Where a joint needs painting, we can suggest a paintable sealant, as silicone cannot be painted.

Do you reseal Cookham Dean homes as well as the village?

Yes. Cookham Dean is part of our regular round, and we plan visits so outside joints and bathrooms can be done in one trip.

How soon can I use the bath?

Usually after around 24 hours. We will confirm the cure time before we leave, along with simple tips for looking after the new bead.
