Compare porch options, row by row

Reading the comparisons

Read the row that matters most to you first. If the budget is fixed, upfront cost decides; if you will stay twenty years, lifespan and the months of use weigh more; if you sell within five, resale. Climate fit is the row most people skip and should not: the months a screened porch is usable in Minnesota and in Georgia differ by half a year, and the regional notes explain why. When you have a winner, the calculator turns a porch into a bracket, the service page explains what its proposal must specify, and a matched professional can price both options on one site visit if you ask in the brief.

What the rows leave out

Site conditions: eave height, siding, frost depth, wind zone and access move every option by a similar amount and are priced on a visit. Taste: the appearance row describes what each looks like, not which looks better. And the rooms behind: a screened porch and a sunroom on the same wall darken the same living room, and only a drawing shows by how much. The quiz covers that question, and the polls show how other planners weighed it. HomeLight's 84% recovery figure for a screened porch and HomeAdvisor's 49% for a sunroom appear in several pairs because they frame the biggest decision on the site.

How do I check a real proposal against these tables?

A proposal answers the same rows the tables do, so read them side by side. Put the bid next to the upfront-cost cell for your option: a new screened porch quoted well above HomeGuide's $10,000 to $35,000 range needs a reason in the drawings, such as a gable tie-in or masonry piers, and one far below usually omits the roof, the electrical or the permit. Then set the install-time row against the schedule in the proposal. Design Builders' 3 to 8 weeks is construction only, so a bid promising a finished roofed screened porch in two weeks is either a prefabricated system or is skipping inspections.

Maintenance and lifespan rows become questions about materials. If the table says rescreening every 6 to 10 years, the proposal should name the mesh and say whether panels are removable. If the table says glass seals last 15 to 25 years, the sunroom proposal should state the glazing unit and its warranty term. The resale row is the one to keep to yourself: HomeAdvisor's 49% return is a reason to buy a sunroom for use, not a number a builder can change. Any row the proposal cannot answer is a line to request in writing before comparing it with another bid.
