What new build mastic looks like in Dinton

How we quote for new build mastic
Call for a quick quote. What matters most is:
- When we can work, for business premises
- The product the joint needs
- How many rooms, windows or areas are involved
- Whether the work is at height
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- Whether it has been sealed before
- The address or postcode of the job
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
If you’re in Dinton and need new build mastic, call 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
Aftercare tips
So the new joints stay in good condition:
- Keep pictures and emails about snagging items
- Open a window or run the fan after bathing
- Watch for new gaps as the house dries out
- Clean sealant with mild detergent, not abrasives
Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
What sealant work cannot fix
In fairness, some problems need a different trade:
- Cracking that points to a structural problem
- Baths and trays that move too much for sealant to cope with
- Cracked trays, tiles or worktops
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

How much does new build mastic cost in Dinton?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or send us an email and tell us what needs doing and where.
Do you work through snagging lists?
Yes. Photos of each sealant item help us quote. If something isn’t sealant, we will say so.

Yes. We cut out all the old sealant and clean the joint before resealing.

Yes. Each job is guaranteed for twelve months.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Why act early in Dinton
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. Where a wall is exposed, as many are in small places like Dinton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
