Window mastic for homes and businesses in Farlington
From a single sill to a whole house of windows, you will get a clear quote before we start. Just ring 0345 464 0079 or email us and tell us how many frames there are and how they’re reached for window mastic in Farlington. If you’re dealing with gaps between the frame and the inside reveal and white mastic on grey or black frames, we can help.
Houses in smaller places like Farlington can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
All of our work is guaranteed for twelve months.

What affects the cost of window mastic
Jobs vary more than people expect. What affects the quote:
- The type of sealant required
- Access and height
- Working hours on commercial sites
- The number of rooms or windows
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Any previous sealing or DIY work
- Where the property is
- The type of property

Leave it or put it right?
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. In an older home around Farlington, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.

What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes a few hours for a few frames, or a day or more for a whole house, depending on the amount of work. Parking around Farlington is generally 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 look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit

Honest limits
In fairness, there are a few things sealant will not fix:
- Rotten timber, which needs a joiner first
- A door that needs adjusting, rehanging or new seals
- Broken hinges, locks or handles
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Farlington questions
Is window mastic in a coastal place like Farlington any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you help a landlord with a rental near Cosham station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Is the work guaranteed?
Yes. All our work carries a 12-month guarantee, and we’re ARBOMaster approved applicators.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or email us.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Windows and doors in Farlington
Farlington is within about 1 mile of 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Solent Infant School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of St Andrew, 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 Cosham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Surface by surface
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We’ll point out any rot we find, as that is a job for a joiner.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
