A homeowner has been thinking about an extension for months. They finally contact a builder and ask the question on their mind: "Roughly how much would a single-storey extension cost?" The builder replies: "Every job is different, we'd need to visit." The homeowner, who wanted a rough idea before inviting anyone round, contacts someone else.
Budget questions come first for most homeowners. How a builder answers them shapes the whole conversation.
Why homeowners ask about cost first
Building work is expensive and unfamiliar. Homeowners do not know whether their idea costs a little or a lot. They want a rough idea before investing time in visits, drawings and quotes. They also want to know whether they can afford it at all.
Why builders avoid the question
Builders worry that any number will be taken as a quote, and that every job has variables that change the price. Both concerns are fair. But avoiding the question entirely leaves homeowners in the dark.
A better approach
Share typical ranges, explain what drives cost and offer a visit for a proper quote. This gives homeowners what they need without committing to a figure.
Example conversations
These are examples a builder might adapt, using figures from their own published information.
Homeowner: How much does a single-storey extension cost? Assistant: The projects page gives typical ranges for single-storey extensions, based on recent work. The final cost depends on the size, the finish, the ground conditions and whether plans are needed. The team can give you a proper quote after a visit. Would you like to arrange one?
Homeowner: What makes an extension more expensive? Assistant: The main factors are size, the type of roof, the kitchen or bathroom fittings if included, ground conditions and access to the site. The projects page explains these in more detail.
Homeowner: Can you work to a budget? Assistant: Yes. If you share the budget range you have in mind, the team can suggest what's achievable and where you might save. It helps them tailor the visit.
Asking about budget
Many homeowners are reluctant to share a budget, worried it will anchor the price. Asking gently, with a reason and with ranges, helps. Techniques from other sectors are useful here, such as those covered in budget questions that scare off the wrong agency clients.
Capturing the details
SpideyChat for contractors and builders answers cost questions from your own pages, sharing only the ranges you publish, and captures project details for a proper quote: type of work, location, size, timeline and budget range. More on answering price questions this way is in AI receptionist pricing questions.
Qualifying before a visit is covered in project enquiries that need qualifying before a site visit, and the cost of slow replies in what an unanswered building enquiry costs a contractor.
Publishing ranges
If you publish ranges, base them on real recent projects and update them as costs change. Include what is and is not included, such as design fees, planning or finishes. Honest ranges attract homeowners with realistic budgets.
The value of honesty
A builder who is honest about cost from the start builds trust. Homeowners who feel they have been given a straight answer are more likely to invite that builder to quote, and more likely to accept.
Getting started
Write a short page on typical project costs and what affects them. Then let homeowners get honest answers at any hour. See the options on the features page, or try SpideyChat on your own site.
