Questions from Charlton-on-Otmoor

What colour sealant will you use?

Are you insured?
Yes. Full insurance covers our work.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Should I wait before resealing?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.

New build mastic in Charlton-on-Otmoor, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. We work on plot handovers, bathrooms & en suites and windows & doors, and common reasons people get in touch are beads laid onto grit and dust from the build and second-fix sealing on new plots.
For a small place like Charlton-on-Otmoor, the journey and access are planned in advance, and the work itself is the same as on any site.
Your job is guaranteed for a year, as with all our work.

How it works
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. It usually takes anything from a few hours to several days, depending on the number of plots. In a small place like Charlton-on-Otmoor, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Leave it or put it right?
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times for the lot. Around Charlton-on-Otmoor, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What the job involves on each surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk in a colour to suit.
Plot handovers
Send us the schedule and any sealant specification for a quote. Sealant work across the plot is covered as agreed.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Looking after it afterwards
After the cure time, these simple habits help:
- Look at the sealant regularly in the first couple of years
- Don’t wait for the house to settle if water is getting through
- Record problems with dated photos
- Open a window or run the fan after bathing
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you so report it promptly.
