The questions to ask a dormer company

The right questions, asked the same way to every shortlisted company, are the cheapest due diligence you will ever do. Here are the ones that actually separate the field.

Short answer

Ask about the company (track record, team, certifications), the project (build method, lead detail, lead time), and the money (payment schedule, warranty, what happens if it goes wrong). Use the same list with every shortlisted company so the comparison stays fair.

About the company

How long has the company been trading? How many dormers do they fit a year? Will the team that visits today be the team that fits? Are they part of a trade body, and which scheme covers the warranty?

About the project

Prefab or built on site? What insulation R-value, glazing U-value? How will the lead be detailed — apron grade, upstand height? What is the lead time and how long does the install take? What is the contingency if the weather is bad on install day?

About money and warranty

What is the payment schedule? What does the warranty cover, for how long, and is it insurance-backed? How does after-care work — call, email, ticket? Is there a service charge for visits after the warranty period?

FAQ

Veelgestelde vragen

01Is it appropriate to ask all these questions?
Yes. A serious company welcomes them — it filters out time-wasters and lets them show their experience. If a question makes a company defensive, that is information too.
02What if I do not understand a technical answer?
Ask them to explain it as if you do not work in construction. A good installer can. A great one will offer the analogy before you ask.
03Should I ask the same questions to all three companies?
Yes — same questions, same order. Otherwise you are comparing three different conversations, not three quotes.
Conclusie
Asking the same questions every time turns three sales conversations into one comparable table. The company you want is usually the one whose answers were the most boring and the most specific.
