Preston homes and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Goodnestone Park (about 4 miles south) nearby, there’s older building stock in the area around Preston as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
In the older streets around Church of St Mildred, the joint between an old wall and a newer frame is generally the first place rain gets in. Schools such as Preston Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

How much does sand mastic cost in Preston?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or send us an email with a short description of the job.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
Which is right for my windows, sand mastic or modern sealant?
It depends on the window. Period windows in stone or brick usually suit sand mastic, while modern frames normally get a flexible sealant.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do I need permission for sand mastic on a listed building?
Your local planning authority is the one to ask. They’ll tell you if consent is needed.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Leave it or put it right?
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Where a wall is exposed, as many are in small places like Preston, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit generally makes better use of the time than several visits. We will give you a clear price for the lot.

Brick reveals
Sand mastic is also used where timber frames meet brick. It gives a traditional finish.
Tenement and terrace windows
Upper-floor windows need access planning. Let us know the floor and we’ll confirm access.
The process
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a single window, longer for several. Somewhere like Preston needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
