Caulk & Sealant Project Checklist
Answer a few real project questions to identify product specifications you must check. This tool does not automatically certify a silicone, acrylic, polyurethane or hybrid product for your home.
Stationary seals versus moving doors
The US Department of Energy distinguishes caulking stationary openings from weatherstripping movable door and window parts. Filling an operable gap with fixed caulk can make it unusable. If your door needs moving-part seals, see our weatherstripping planner instead.
Separate a moving sash from a stationary joint
An air leak beside an opening sash and a gap between stationary frame and trim can look similar. They need different decisions. Applying caulk across the sash's moving contact can obstruct opening or drainage; a suitable replaceable weather seal may be the relevant route instead.
For a stationary joint, narrow the options by the actual substrates, expected movement, joint size, weather exposure and whether the cured product can receive the intended paint. The checklist flags considerations; it does not test adhesion or certify that a generic sealant is compatible with the assembly.
Check before the next step
Confirm the joint's function and follow the window, door and sealant manufacturers' directions. Obtain assembly-specific advice for fire, structural, glazing, waterproofing or other specialist details.
Finish the purchase calculation after product selection
When the exact product, approved joint shape and cartridge fill are known, use the Caulk Calculator to estimate whole cartridges.

The checklist never assumes a universal movement rating, cure time, price or material compatibility.
