Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. In an older home around Quarrendon Estate, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

How it works
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. Most jobs take a few hours for a handful of frames, longer for a whole house. For a job in Quarrendon Estate, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Mention any sign-in or site rules at work premises
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Don’t aim a pressure washer at the joints
- Wash the frames with mild soapy water
- Avoid harsh chemicals near the mastic
- Air rooms to keep condensation down around windows
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Quarrendon Estate homes and the weather
With historic houses such as Waddesdon Manor (about 4.8 miles west) nearby, there’s older building stock in the area around Quarrendon Estate as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

When to call us in Quarrendon Estate
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
Any of these means the joints need attention:
- Sealant in the wrong colour for the frame
- Gaps between the frame and the inside reveal
- Old mastic that has gone black or come away
- Untidy mastic left by window fitters
Homes close to St Peter's include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How we quote for window mastic
There’s no set price list, because no two jobs are the same. What we look at:
- The amount of work
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and send you a clear quote before we start.
Helping us quote
To make quoting easier, let us know:
- The type of property
- Whether it has been sealed before
- The problem you’ve noticed
- Pictures of the joints, sent by email
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or email us.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Broken hinges, locks or handles
- Condensation trapped between the panes
- Penetrating damp from a failed cavity tray or render
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.

How many windows can you do in a day?
That depends on the number of frames, how they’re reached and the state of the old mastic. You will know the timing when we quote.
Can you reach windows above the ground floor?
Generally, yes. Access is planned before we start, so mention the height and anything in the way.
Can you get sealant to suit coloured frames?
Normally, yes. Mention the frame colour when you ask for a quote and we’ll use the nearest match.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Is the new sealant paintable?
Most silicone can’t be painted. Let us know beforehand, and we will use a paintable product where it suits.
