New build mastic in Wytham, done properly
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. Common call-outs are for gaps behind new kitchen upstands and sealant that never bonded to the surface, across skirting & floors, show homes and plot handovers.
Work in a small place like Wytham just needs the journey and access planning, and the work itself is the same as on any site.
Each job carries a 12-month guarantee, whatever its size.

Can I do it myself?
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What we do, step by step
We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job usually takes a few hours in a single home, and we tell you how long to leave it before we go. In a small place like Wytham, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can

Advice
FAQs for Wytham
Do you work for landlords with property near Oxford Parkway station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Will you come out to Wytham?
Yes. Wytham 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.
Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early as timber and plaster dry out. Poor preparation at handover adds to it.
My new home is still under warranty. Should I contact you?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Why deal with it now?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a small place like Wytham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is normally more efficient than separate visits. We’ll give you a clear price for the lot.
Why book with us
- ARBOMaster approved applicator
- Sealant colour chosen to suit
- Sanitary silicone with an anti-fungal additive in wet areas
- We’re fully insured

Surface by surface
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and prime where the product needs it.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.

Look out for these signs:
- Leaking shower tray seals in a new home
- Cracked caulk along new skirting
- Sealant applied over dusty or wet surfaces
- Cracked sealant around new window and door frames
For new homes near Oxford Parkway station, it’s worth checking the sealant early, while snags are still fresh.

Looking after it afterwards
To keep the joints looking good and working properly:
- Don’t seal over failed sealant yourself
- Get a leaking seal dealt with straight away
- Photograph failed sealant before it’s redone
- Put sealant faults on your snagging list early
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
