What affects the cost of new build mastic
Jobs vary more than people expect. What affects the quote:
- How many rooms, windows or areas are involved
- When we can work, for business premises
- Access and height
- The size of the job
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Pictures of the joints, sent by email
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
Asking for a quote is easy: let us know what needs doing and where. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
How we handle new build mastic in Fratton
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on bathrooms & en suites, windows & doors and kitchens, and the jobs we see most are cracked caulk along new skirting and plot mastic for developers ahead of handover.
In smaller places like Fratton, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Different surfaces, different methods
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed.
New build mastic around Fratton
Fratton is within about 2 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Fratton, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Fratton station, the sealant around baths, showers and frames is worth checking in the first year or two.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Put sealant faults on your snagging list early
- Follow the cure time we give you
- Check bath and shower seals every few months as the house settles
- Open a window or run the fan after bathing
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.

We also work for property managers and facilities teams in Fratton and across Portsmouth. We can quote a run of properties together.

The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the number of plots. For a job in Fratton, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children

What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.

Are you insured?
Yes. We’re fully insured for every job we do.
Do you work for hotels and businesses?

When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Plumbing faults behind the sealant
- Cracked trays, tiles or worktops
- Your warranty claim itself, which is between you and the builder
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.

- Plot handovers
- Kitchens
- Show homes

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
