Hi, I had too much heavy stuff in a closet and now the floor is sagging in the middle. Is there any cheap and fast way to fix this?
If the floor is sagging that means the support structure is damaged or missing. If you cannot get at it from underneath you're going to have to remove the floor planks and maybe the sub-floor in order to repair or replace the support. In a small area such as a closet you may be able to get away with placing new oak planks oriented 90 degrees to the old floor. However, this will raise the floor and may interfere with the door and saddle.
If there's a obtainable guy around, he can do away with the door and trim approximately 3/8 inch of fabric off of the backside.to circumvent the timber from splintering scribe a at present line with a pointy blade, utilizing a at present side and prepare protecting tape including the scribed line. utilizing the at present side returned, clamp it to the door and now make the cut back, utilizing an excellent cut back trim blade in a around observed. this permits a suitable cut back without splintering. some professional's will seal the backside edge of the door right this moment to circumvent destiny humidity subject concerns to go into the door and probably reason warpage,
Pac man is right. You should check from the underside if at all possible(crawlspace, basement, etc.) Otherwise the short answer is no. You will have to pull out the flooring and make a fix to the subfloor by adding a support and likely have to replace the section of subfloor anyway due to warping if it's been like that for any real length of time.
