Your questions about window mastic in Parkgate
Is there a guarantee on window mastic in Parkgate?
All our work, in Parkgate and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Will you come out to Parkgate?
Yes. Parkgate is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
When is the sealant fully cured?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
Do you work on first-floor windows?
Yes, in most cases. Access is planned before we start.
What information do you need?
Let us know what needs doing and where, with photos by email if possible. We’ll ask anything else we need to know.
Can I paint over the new sealant?
Not if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
How we handle window mastic in Parkgate
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and we give a one-year guarantee on the work. If you are dealing with rushed sealant from a window installation and black, perished sealant on frames, we can put it right.
Around Parkgate, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Other services in Parkgate
Different surfaces, different methods
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Why deal with it now?
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. Around Parkgate, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.
Why book with us
- Old sealant always removed completely
- Arbo and Everbuild products

How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take most of a day for a typical house, less for a few frames. Somewhere like Parkgate needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Before we arrive
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
Getting a quote
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.

Historic houses like Smallhythe Place (about 3.7 miles south-east) are a reminder that the area around Parkgate has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.

Do you need window mastic in Parkgate?
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Most people get in touch after spotting one of these:
- Gaps between the frame and the inside reveal
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
- Old mastic that has gone black or come away
If you look after a building such as Homewood School, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- Is the old sealant removed completely?
- Which sealant they’ll use, and why
- How much experience the applicator has
- When the joint can take water or movement
What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

- A failed sealed unit that has misted up
- A sash or casement that won’t close properly
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- Which sealant suits the joint
Doing several joints on one visit usually makes better use of the time than several visits. We will send you a clear quote for the lot.
