Ifield Window Mastic
Problem with your window and door frames in Ifield? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Leaking joints at the ends of sills
- Draughty joints inside around the window
- Old mastic that has gone black or come away
Window mastic in Ifield
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. The sealant then grips the two sides it should. If you are dealing with cracked or shrunken mastic around the frame and black, perished sealant on frames, we can help.
In a smaller place like Ifield, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Ifield questions
Can you help a landlord with a rental near Ifield station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Do older homes in Ifield need their sealant replacing?
In most cases, yes, if it hasn’t been done for a while. Sealant does not last for ever, and its life depends on use, cleaning and weather, and many homes in Ifield may already be on their second or third set.
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Can you reach windows above the ground floor?
Generally, yes. Access is planned before any work starts, so mention the height and anything in the way.
Can new window sealant be painted?
That depends on the product. Silicone isn’t paintable, but some hybrid sealants are. Mention any painting plans before work begins.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or send us an email.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
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.
Signs you need window mastic in Ifield
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. That’s what backing rod is for.
Signs it’s time to call us include:
- Rain getting in at the frame or under the sill
- Cracked or shrunken mastic around the frame
- Rushed sealant from a window installation
- A bead that doesn’t match the frame
Homes close to St Margaret's Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Window mastic in Ifield: local notes
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. Crawley, which Ifield is part of, is one of England’s post-war new towns. Many homes date from the post-war decades, and many will have had their original windows replaced. The mastic around replacement frames ages too, and gaps at sills and frame heads are where water gets in.
For site and facilities teams at buildings such as St Margaret's CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Ifield station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What affects the cost of window mastic
You will get a clear quote before work begins. It takes into account:
- When we can work, for business premises
- The type of sealant required
- Whether there’s mould to deal with
- How many areas need sealing
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Roughly how big the job is
- The address or postcode of the job
- Any previous sealing or DIY work
- A few photos by email, if you can
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will explain what’s involved and give you a clear quote.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Ventilate rooms so frames do not stay wet inside
- Keep timber frames painted
- Use gentle cleaners on frames and sealant
- Make sure the drainage slots are not blocked
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.

What else we do in Ifield
How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. A visit to Ifield is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks

Advice
When something else is needed
In fairness, there are a few things sealant will not fix:
- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame
- Broken hinges, locks or handles
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.
Joints and surfaces we work on
- Window sills
- Patio & French doors

Leave it or put it right?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In a smaller place like Ifield, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
