Sidlesham Common questions
Is Sidlesham Common within the area you cover?
Yes, Sidlesham Common is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do new build mastic in Sidlesham Common?
Yes, Sidlesham Common is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
New build mastic in Sidlesham Common
Across Sidlesham Common, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. We work on bathrooms & en suites, skirting & floors and show homes, and the jobs we see most are gaps behind new kitchen upstands and internal frame sealant that has split.
Around Sidlesham Common, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
All of our work is guaranteed for twelve months.

New build mastic in Sidlesham Common: local notes
Sidlesham Common is within about 2 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Around Sidlesham Common, as everywhere, new build mastic is only as good as the preparation behind it.
Sidlesham Common is about 3 miles south of Chichester, in West Sussex. Jobs in Sidlesham Common get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. We cover 371 towns and villages across West Sussex. Our Portsmouth page covers work nearby.

Local landmarks in Sidlesham Common
Around Sidlesham Common, our work takes us to homes and buildings near The Blacksmith's Arms Public House. For rail, the closest station is Chichester station, about 2.6 miles north. A little further out are Chichester Cathedral Treasury (2.9 miles north) and Chichester Castle (3.2 miles north). Open spaces near Sidlesham Common include Nutborne Marshes.
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Avoid scourers and strong chemicals on sealant
- Follow the cure time we give you
- Avoid running a DIY bead over the old one
- Ventilate bathrooms well, especially in the first year
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
How it works
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours in a single home for a typical job. Somewhere as small as Sidlesham Common, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

Work for landlords, hotels and businesses

What we are called out for in Sidlesham Common
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
Keep an eye out for these signs:
- Gaps behind new kitchen upstands
- Leaking shower tray seals in a new home
- Cracked caulk along new skirting
- Cracks appearing as a new home settles
For new homes near Chichester station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before booking
- Who does the work, and how experienced they are
- How the joint is cleaned and prepared
- Which sealant they’ll use, and why
- Whether VAT is included
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What the job involves on each surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
