DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we cannot put right
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Baths and trays that move too much for sealant to cope with
- Structural cracks in walls or ceilings
- Cracked trays, tiles or worktops
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.
Surfaces we seal
- Bathrooms & en suites
- Kitchens
- Plot handovers
- Show homes
- Windows & doors
- Skirting & floors
What the job involves on each surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing so the sealant lasts.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Quotes for new build mastic in Chalfont Common
You will get a clear quote before work begins. It takes into account:
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- The number and length of the joints
- Which sealant suits the joint
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Whether it’s a home or a business
- Whether it has been sealed before
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or drop us an email.
Chalfont Common questions
Is Chalfont Common in your area for new build mastic?
Yes. Our work covers London and the South East, and Chalfont Common is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
I let a flat near Gerrards Cross station. Can you help?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
How do I get a quote for new build mastic in Chalfont Common?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
When is the best time to reseal in a new build?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Work for landlords, hotels and businesses
For anyone letting property in or around Chalfont Common, several properties can go on one quote. Just tell us the addresses and what each one needs.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Where a wall is exposed, as many are in small places like Chalfont Common, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
