Editorial standards

How these guides are written

Worth stating plainly, because plenty of home-improvement content on the web does none of this.

Every factual claim is linked to its source

Where a guide cites an action level, a standard, a code requirement or a tax provision, the source is hyperlinked in the text and listed again at the foot of the page. That means the EPA radon action level, the IICRC water damage categories, the ICC residential code, OSHA’s asbestos standards and the relevant sections of the US tax code — linked to the issuing body, not to another blog repeating it.

If a guide states a number and does not show you where it came from, that is a defect. Tell me and it gets fixed.

The dates are the real dates

The published date on a guide is the date it actually went live, and “last updated” is the date the file was genuinely last changed. Nothing here is post-dated to look fresh, and nothing carries a review claim unless a review actually happened.

What these guides are not

  • Not professional advice. They are written to help you understand a problem well enough to have a competent conversation about it — not to replace the licensed professional who should assess it.
  • Not a substitute for inspection. No article can see your foundation, your wiring or your crawl space.
  • Not sponsored. No brand has paid for a mention in any guide on this site, and there are no affiliate links in them.
  • Not lead generation. Reading a guide does not put you in a contractor’s callback queue. Nothing here collects or sells your details.

Corrections

If something here is wrong — a figure, a code reference, a standard that has since been revised — the fastest fix is to say so. Email kapil@kapilseo.com. Corrections from people who have actually done the work, or actually paid the bill, are the most useful mail this site gets.

How to use them

Guides answer the question the calculator cannot

The estimators on this site tell you what something is likely to cost. They deliberately do not tell you whether you should do it, which of two approaches is better, or whether what you are looking at is actually a problem yet. That is what the guides are for.

In practice the two work best in this order:

  • Start with the guide when you are not sure what you are dealing with. Is that foundation crack structural or cosmetic? Does the insurance policy cover this kind of water damage? Is the ceiling likely to contain asbestos? Pricing a repair you may not need is wasted effort.
  • Move to the calculator once the scope is clear. When you know it is a repair rather than a replacement, or closed-cell rather than open-cell, the estimator can give you a figure that means something.
  • Come back to the guide before you sign. Several of these cover the comparisons that decide long-run cost rather than upfront price — composite against wood, fiber cement against vinyl, trenchless against open-cut.

Every guide links directly to the estimator for its subject, and every estimator links back to the guides that explain it.

These guides are general information, not professional advice. Building codes, permit requirements and safety regulations are set locally and change over time — your building department and a licensed professional are the authorities for your property. Sources are linked at the foot of each guide so you can check them directly. Full disclaimer →
