Common questions. Straight answers.

Screen rooms and basic patio enclosures run about $15,000-$30,000. Three-season rooms run $25,000-$50,000. Fully insulated four-season rooms and glass additions run $40,000-$100,000 or more depending on size, glazing, and foundation work. The on-site estimate sets the written price.

Yes. A crew visits your property, reviews the footprint and options, and hands you a written quote with no obligation and no trip fee for your zip.

Often yes. Existing patio covers with a solid roof and adequate footings are frequently converted to screen rooms or three-season enclosures at lower cost than a new addition. The crew confirms suitability at the on-site visit.

A four-season room is fully insulated, climate-controlled, and can be used comfortably year-round. A three-season room typically uses screen or vinyl panels and is not heated or air-conditioned, making it comfortable in mild weather but not during heat waves or cold snaps. In San Diego the difference matters less than in colder climates, but East County heat still makes four-season insulation worthwhile.

Low-E coated glass is the standard recommendation for San Diego. It reduces UV and heat gain while keeping the view clear, cutting afternoon heat in rooms that face south or west. Coastal properties benefit from tempered safety glass with stainless hardware to resist salt air. Your crew will recommend the right glazing for your orientation and budget.

Most sunrooms require a concrete foundation, either a poured slab or perimeter footings. Existing patios with a solid concrete slab often qualify as-is, reducing foundation cost. The crew assesses the existing surface at the site visit and confirms whether new foundation work is needed.

Yes for most sunroom types. Additions, enclosed patio covers with a solid roof, and structural conversions require a building permit. Screen rooms may also require one depending on the jurisdiction. Your crew handles the permit when the scope calls for one.

A prefab or screen room installs in a few days once the pad is ready. A custom four-season addition with permits takes four to ten weeks from permit approval to finish. Your crew sets the timeline at the on-site estimate.

Generally yes, especially four-season rooms that add permitted livable square footage. Appraisers count permitted additions differently than unpermitted structures, so pulling the permit correctly matters for resale value.

No. Sun Room SD is a referral service, insured not licensed, cslb.ca.gov. We match you with insured local sunroom crews and help you get a clear written quote. The crew you hire does the work.

The crews we match carry general liability and workers comp, and we confirm coverage before work starts. You can verify any California contractor license at cslb.ca.gov.

Getting matched and getting the on-site estimate and written quote costs you nothing. You only pay the crew you choose for the actual sunroom work.
