Manufacturing · Construction Materials
The homeowner got three window quotations and ours was the only one without a drawing.
Windows are bought rarely and regretted for years. A homeowner wants to know whether the frame will rattle, whether the glass will keep out noise, and who will come back if the sliding track sticks.
Scope, fee, reporting and term are agreed in writing after we have read your brief and spoken to you.

In one paragraph
Door and window manufacturing for construction covers aluminium, uPVC, steel and composite frames, glazing and fittings made to measure and installed in homes, offices and projects. GullySales works on how fabricators are found by homeowners, builders and architects, how a measured quotation is presented, and how site visits become orders.
A builder buying for a project asks different things: the frame system, the glass spec, the rate per square foot and the installation schedule.

Who it is for
This is written for you if doors & windows is what you make or sell.
- Aluminium window and door fabricators
- uPVC window manufacturers and installers
- Steel door and window makers for projects and industry
- Makers who supply builders and also sell through a showroom
- Fabricators who have started offering glass, mosquito mesh and fittings together
Not for
It is not the right fit if.
- A fabricator who does not measure on site. A window that does not fit is the first complaint a buyer remembers.
- A maker who will not state the system, profile or glass they use.
How buyers choose
What decides the sale of doors & windows.
The site measurement and drawing
The fabricator visits, measures every opening, and sends a drawing with sizes and types. The buyer approves the drawing before the order.
Frame system and glass specification
They ask which profile series, what glass thickness and whether it is toughened or laminated, and compare it across quotations.
Rate per square foot and what it includes
A rate per square foot is the common basis, and each quotation includes different things. Hardware, mesh, installation and taxes are the usual traps.
Installed work and after-sales
The buyer asks to see a home with the same system installed, and who comes if a window needs attention.
Where orders are lost
What usually goes wrong when you sell doors & windows.
In the words owners use on the first call.
“The quote has a rate per foot and no drawing”
A homeowner cannot judge it. A quotation with a drawing, opening by opening, looks more reliable even when the price is higher.
“We lose to the cheaper fabricator who uses thinner profile”
The buyer cannot see the wall thickness of the profile. Without a clear specification, the lower number wins.
“Builders pay slowly and change sizes”
Project orders alter as the building changes. The fabricator needs a written revision and payment routine.
“Reviews mention a delay and nothing else”
A single complaint about a late installation sits at the top. Replies and recent reviews balance it.
The scope
The work we would propose for doors & windows.
Measured on qualified enquiries, quotation requests, follow-up on each quotation, orders won and, where you sell through dealers or shelves, repeat orders by channel. Anything here that needs a platform, directory or tool we have not used with you is confirmed with you before it goes in the scope.
- A page per system: aluminium, uPVC, steel, sliding, casementProfile series, glass options, sizes and photographs of installed homes.
- Measurement visit booking and follow-upA booking page that asks the number of openings and location, with calls after the drawing is sent.
- Google Business Profile and reviewsPhotographs of installed work, correct service area and replies to every review.
- Builder and architect packSystem specification, rate by type, sample corner and a project reference list.
A quotation format that states profile and glass
Opening-wise sizes, system, glass, hardware, mesh and installation, so comparison is fair.
What we do
What you get for doors & windows.
Each deliverable and what it is there to change.
A system comparison page

A review and after-sales routine
A request after installation and a clear number for service calls.
How the result is measured

How it works
From your first message to the first report.
No open-ended retainer. Every step gives you something in writing.
First
Your brief
You tell us what you need in a few short steps: your business, what you want, where enquiries come from and how they are handled.
After the brief
A conversation and a written scope
We read it, then talk with whoever handles your enquiries. If you want our help, the scope, the fee and the reporting come in writing, and nothing starts before you have read them.
Before work starts
Baseline recorded
The numbers this work is meant to move, such as enquiries, quotations, orders, visits or renewals, written down so every later report has an honest comparison.
After the baseline
The first fix goes live
The fix we agreed to start with is put in place and measured against the baseline, whether that is a reply, a follow-up, a page, a listing or the handover between marketing and sales.
As agreed
Report against the baseline
What moved, what did not, and what changes next, in plain words. How often you get it is set in writing before work starts.
At renewal
Renew on the numbers
The term ends and you decide whether to continue from the results. The length is agreed in writing before anything starts.
What we need from you
What to have ready before we talk.
None of it has to be tidy. We read what you have.
- Systems and profile series you use
- Glass and hardware options you offer
- Last ten quotations and outcomes
- Photographs of installed work
- Builders and architects you supply
Export and new regions
Selling doors & windows beyond your home market.
Where you sell decides standards, documents, payment terms and freight. We work from Bengaluru and have no overseas office, so for a new region we start from your own enquiries, your existing buyers and the directories you already use.
Fabricated windows seldom travel
Made-to-measure windows are hard to export. Extruded profile, hardware and components, if you make them, are likelier to be asked for.
Project supply
Some buyers abroad source windows for housing projects. Your own export enquiries show whether you have been asked.
