Your questions answered
Does your area include sites such as Lower Soldridge Business Park, near Gilbert Street?
Yes. Estates, retail parks and business parks around Gilbert Street, Lower Soldridge Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Is a smaller place like Gilbert Street outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How do I request a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Facade sealing in Gilbert Street, done properly
Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. The enquiries we see most involve hard, chalky sealant that no longer flexes and cold air coming in at window perimeters, on shopfront frames, stone and brick facade joints and cladding panel joints. A specialist sealant contractor works differently from a general builder: on jobs in Gilbert Street, preparation and product choice get the time they need.
Conversions of older rural buildings near smaller places such as Gilbert Street bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What else we do in Gilbert Street
What happens if it’s left?
Topping up a failed joint typically buys very little time. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. Older rural buildings around Gilbert Street move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Contractors’ notes for Gilbert Street
At about 51 miles from central London, Gilbert Street is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.
Projects at schools like Ropley Church of England Primary School work to term dates, so mastic is programmed tightly. Hospital estates such as Alton Community Hospital, 4.8 miles to the north-east of Gilbert Street, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Gilbert Street is about 6 miles south-west of Alton, in Hampshire. Commercial clients in Gilbert Street use us for work on facade joints, as part of our coverage of Hampshire. Gilbert Street is one of 723 places in Hampshire on our list for facade joints. We also cover Southampton, around 18 miles from Gilbert Street.

On site: what to expect
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For work around Gilbert Street, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Getting the site ready
- Make sure the joints can be reached
- Tell us your opening times and when work is allowed
- Let us know about inductions and permits
Getting a fixed quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or send photos by email with what you know.

Common problems we fix in Gilbert Street
When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.
Look out for the following:
- Patch repairs that keep failing
- Damp patches beside frames after rain
- Failed seals around shopfront and entrance frames
- Draughts around frames and panels
Older buildings in the area around Gilbert Street, such as Bentworth Hall, 4.2 miles north of Gilbert Street, need care when sealed: the product has to suit soft or historic materials.

What affects the price in Gilbert Street
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Joint width, depth and condition
- Phasing around occupants
- The product specified
- Induction, permit and paperwork requirements
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- The asbestos register, for older buildings
- Access details, including height
- Rough lengths or quantities, or drawings if you have them
- Specification clauses that apply
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
What the job involves on each surface
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints.
Window and door perimeters
Frames grow and shrink with temperature, and the perimeter joint has to follow. Rod placed at the right depth lets the bead stretch as the frame moves.
Site staff or a sealant specialist?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
