Window mastic in Bitterne Park, done properly
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on aluminium frames, timber windows & doors and uPVC windows, and common reasons people get in touch are mastic that has split away from the wall and draughts coming in around windows and doors.
Houses in smaller places like Bitterne Park can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Each job carries a 12-month guarantee, large or small.

Window mastic in Bitterne Park: local notes
Bitterne Park is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. With historic houses such as South Stoneham House (about 0.9 miles north) nearby, there’s older building stock in the area around Bitterne Park 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.
Homes close to Church of Ascension include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Bitterne station, renewing tired window mastic between tenants heads off draught and damp complaints.

Landlord and commercial work in Bitterne Park
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
For anyone letting property in or around Bitterne Park, several properties can go on one quote. Just tell us the addresses and what each one needs.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Keep timber frames painted
- Paint up to the joint, not over it
- Look round the frames every year or so
- Avoid harsh chemicals near the mastic
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just ring 0345 464 0079 or send us an email.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
What happens on the day
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take most of a day for a typical house, less for a few frames. Parking around Bitterne Park is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on
- Let us know about earlier repairs to the joints

Signs you need window mastic in Bitterne Park
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
Keep an eye out for any of the following:
- Sealant in the wrong colour for the frame
- Draughts coming in around windows and doors
- Untidy mastic left by window fitters
- Black, perished sealant on frames
Managing a site like St Mary's Independent School? Then larger buildings have plenty of frames, and the mastic around each one ages.

What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- A door that needs adjusting, rehanging or new seals
- Faulty window hardware
- Penetrating damp from a failed cavity tray or render
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

What affects the cost of window mastic
We quote each job individually. This is what makes a difference:
- How many areas need sealing
- Which sealant suits the joint
- Whether there’s mould to deal with
- How much there is to do
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear quote before we start.
What to tell us for a quote

- Where the property is
- The type of property
- How many joints, rooms or windows are involved
- The problem you’ve noticed

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Your questions about window mastic in Bitterne Park
Does the coastal weather in Bitterne Park affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Do you cover smaller places like Bitterne Park?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can new window sealant be painted?
It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Tell us if you are decorating and we’ll choose accordingly.
Where are you based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Do you work for landlords and businesses?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
