Full-service, all in one place
Cape Cod weather is unforgiving — wind-driven rain, salt air and seasonal movement find weak points fast. We build with a finish-carpentry mindset: proper flashing, solid sealing, clean lines and openings set square.
We install and replace windows and doors with a clean finish and proper sealing — so everything looks right, closes smoothly, and helps keep your home protected from Cape Cod weather. Upgrades, replacements, adjustments and trim finishing, with clear estimates and organized work.

Trim is what makes a home look “finished.” We handle replacement, repairs and detailed finishing, inside and out — straight alignment, tight joints, clean transitions and smart material choices for exposed areas. If we find soft wood or hidden rot behind the trim, we address it before closing everything up.

From repairs and board replacement to new builds, railings, stairs and refinishing, we deliver deck work that looks right and holds up. We keep the job site clean, communicate clearly, and help you choose the best option for your home and budget.

I’ve been flipping high end homes for 25 years and I can tell you that Castro was extremely professional, honest and did excellent work at a fair price. I would definitely hire them again.
Steven and his team are true professionals. The work quality and attention to detail shows they take pride in their work. They always communicated throughout the project, and stayed on schedule.
The Castro crew is punctual, clean and respectful to both home and home owner. We had a bay window installed, and siding applied. The work was done within the week.
Great communication and response time. Highly recommend this company!
