Mastic and sealant work in Bordon

Resealing and mastic work across Bordon

For more than a century Bordon was an army town. Bordon Camp was first laid out in 1899 and occupied from 1903, and REME trade training was based here until 2016. Since the army left, the town has been changing fast under the Whitehill & Bordon regeneration plans, and new homes now sit alongside the older streets that grew up around the camp. Mr Mastic covers Bordon, Whitehill and the villages around them from our base in Crawley.

We reseal baths, showers, basins and worktops, replace hardened mastic around windows and doors, and deal with the snagging list that often comes with a brand new house. Every job starts the same way: old or failed sealant comes out in full, the joint is cleaned and dried, and the new bead is matched to the job. We don’t run fresh silicone over old, because it simply peels away.

Garrison-era streets and a town being rebuilt

Bordon forms part of the civil parish of Whitehill, and Whitehill itself began to grow between Bordon Camp and Longmoor Military Camp as they were developed between 1899 and 1903. Much of the older housing dates from the decades that followed, when the camps were busy, and it is a mix of terraces, semis and bungalows. Many of these homes have had kitchens and bathrooms replaced several times, and the sealant around them is often a patchwork of different jobs.

In 2009 Bordon was named a possible eco-town, with an early plan for 5,000 new homes, and the Whitehill & Bordon Masterplan was finalised in 2012. The aim was a town with sustainable housing and business facilities, and part of the plan was to regenerate older, lower-standard homes and streets. That means a large share of the town’s housing is either very new or recently improved.

New homes have their own sealant problems. Timber frames dry out, plaster shrinks and the house settles, and the sealant put in by the builder often splits around baths and shower trays within the first year or two. Our page on new build mastic explains what we check and how we put it right.

Snagging, settling and older refits

On new developments, the jobs we see most are cracked silicone around shower trays, gaps opening behind kitchen worktops, and mastic around uPVC windows and patio doors that was rushed on site. If your home is still under the builder’s warranty, it is worth reporting faults to them first; our new build sealant snagging guide covers what to look for. Once that period has ended, or if the repair didn’t last, we can cut it all out and redo it properly.

In older homes the problem is usually age. Mastic around replacement windows hardens after years of sun, and bathroom sealant goes black where it sits wet. Where a property is part of a block or is managed by a housing provider, we can arrange access and parking with the managing agent so the work is done in one visit.

Schools, public buildings and rented homes

Bordon has a good spread of public buildings with washrooms and kitchens that need resealing from time to time, including the Phoenix Theatre, Whitehill and Bordon Leisure Centre, Oakmoor School on Budds Lane and Hollywater School. For buildings like these, out-of-hours working can be arranged so facilities are back in use as soon as the sealant has cured.

We also work for landlords and letting agents across the town. Resealing between tenancies, or as soon as a tenant reports mould, keeps a small job from turning into damage to floors and ceilings. If you have several properties in Bordon and Whitehill, we can quote for them together.

Questions from Bordon

Do you cover all of Bordon?

Yes. We cover Bordon and Whitehill, neighbouring Lindford about a mile to the north-east, Headley, and on towards Liphook and Alton.

The sealant in my new Bordon home has already cracked. Is that normal?

It’s very common. New houses dry out and settle, and builder sealant often can’t take the movement. We remove it, prime where needed and reseal with flexible sanitary silicone.

Should I go to the builder first?

If the home is still in its warranty period, it’s worth reporting the fault to the builder. If that has ended or the repair failed, we can redo it.

Can you reseal around patio doors and uPVC windows?

Yes. We cut out the old mastic, clean the frame and wall, and apply a weatherproof sealant in a colour to suit.

Do you work in schools and public buildings?

Yes. We reseal washrooms, kitchens and shower areas, and out-of-hours working can be arranged.

How soon can I use my shower after resealing?

Usually after around 24 hours. We’ll tell you the exact cure time for the product we used.

Do you work for letting agents in Whitehill and Bordon?

Yes. We reseal between lets and can quote for a group of properties at once.
