Mastic sealing in Haslemere, done properly
For blocks and buildings in Haslemere and across Surrey, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote, and site visits can be arranged. We work on communal entrances and stairwells, communal kitchens and washrooms and shopfronts below residential blocks, and the usual reasons a site gets in touch are mastic failing across several blocks on an estate and worn sealant at communal door frames. Most enquiries from Haslemere start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Converted and older buildings in and around Haslemere often put modern windows into old walls. Perimeter joints need a sealant that suits both frame and masonry.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

What sets the cost
Your fixed quote is built from the real scope. It allows for:
- Which sealant the job calls for
- Whether the work must be split into stages
- Backing rod, priming and other preparation
- Access and working height
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- Specification clauses that apply
- What the building is and how it’s used
- Any dates the work must fit around
- Photos of the joints, close up and from further back
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or ring 01277 525 020 or send details through our quote form if you’d rather talk the job through.
Why act early in Haslemere
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows and occupiers notice. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

From enquiry to sign-off
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. Work in places the size of Haslemere is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We inspect the joints, building by building, and record what has failed and why.
- You get a fixed quote, priced per building where that helps your budgeting.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Preparing the site
- Let building users know which areas are affected
- For older buildings, check the asbestos register before work
- Have the specification and drawings to hand
Getting a fixed quote
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Advice
Haslemere: questions and answers
Can you work in a care home near Haslemere with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
Is a smaller place like Haslemere outside your area?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Is asbestos a concern with old mastic?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Maintenance after handover
For the best life from the joints:
- Prioritise elevations facing the weather
- Make it easy for occupiers to report draughts
- Share your contractor requirements early
- Track which buildings were done and when
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.
