New build mastic in Colchester
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. If you have skirting joints opening in the first winter and gaps opening as the house dries out and settles, we can put it right, whatever the surface.
Commercial units around a large town like Colchester generally have concrete floors with joints that need filling and resealing as they wear. At home, it’s the same idea on a smaller scale: skirtings, thresholds and shower seals.
Big or small, you get the same one-year guarantee.
What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. For businesses in Colchester, a room closed because of a leak or mould costs more than the sealant, so it pays to replace failing joints before they get that far.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

When it isn’t the sealant
A few problems are outside what sealant work can do:
- Damaged fittings that need replacing
- Leaking fittings rather than failed sealant
- Baths and trays that move too much for sealant to cope with

Can you work on commercial sites?

Who should fix failed sealant in a new build?
Your builder, if you are still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Is it normal for sealant to crack in a new home?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
New build mastic in Colchester: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Colchester Town station, it’s worth checking the sealant early, while snags are still fresh. In and around Colchester, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Advice
What affects the quote in Colchester
Some jobs are bigger than they look, and some smaller. The main factors:
- How many areas need sealing
- Mould in or behind the old joints
- Which sealant suits the joint
- How easy the joints are to reach
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- Any previous sealing or DIY work
- Where the property is
- If it’s domestic, commercial or a hotel
- A few pictures by email, if you can
Every job is quoted individually. Just phone 0345 464 0079 or drop us an email with the details and send photos if you have them.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Don’t seal over failed sealant yourself
- Wipe joints with warm soapy water
- Photograph failed sealant before it’s redone
- Open a window or run the fan after bathing
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
