The "I wish I'd known this before I started" thread – one sentence per post

I'll go first.

"The lead time quoted by the supplier is always a lie – double it."

My supplier said 6 weeks for windows. They arrived in 11. Next time, I'm ordering the day I sign the contract and assuming everything takes twice as long as promised.

Now the crowd speaks:

"Order windows the day you sign the contract, not the day you measure."

I waited for "final measurements." By the time I ordered, the factory was backed up and I lost 5 weeks. Measure twice, order once – and order early.

"The plumber's 'I'll be there at 8' means 'I'll be there between 10 and never.'"

I took time off work to meet him three times. He showed up once. Now I schedule trades for the afternoon and assume morning means noon.

"If it's not in writing, it didn't happen."

My GC promised to move a light fixture. He didn't. I had no proof. Now every single change goes into an email or a text that I screenshot and file.

"Your GC's schedule is a suggestion, not a promise."

I planned my life around his "firm" dates. Then everything slipped. Now I treat the schedule as a rough guide and don't book anything important until the work is actually done.

"Add 30% to every budget line item and you might only go over by 10%."

I budgeted $15,000 for tile. Spent $19,000. Contingency is not optional – it's survival.

"The cheapest quote is never the cheapest quote."

I hired the lowest bidder. He cut corners, I paid to fix them. The second‑cheapest quote would have saved me money in the long run.

"If a trade doesn't return your call within 24 hours, they never will."

I waited three days for a callback from an electrician. He never called. I should have moved on immediately.

"Take photos of everything before demo – you'll forget what it looked like."

I thought I'd remember where the pipes were. I didn't. Now I have a folder with 200+ photos and I refer to it constantly.

"The backordered tile will arrive the day after the tiler leaves."

I ordered tile 8 weeks early. It came 9 weeks later. The tiler had moved on to another job. I waited 3 more weeks for his return.

"Your spouse will care about paint colours more than you think."

I chose the paint alone. Big mistake. Now my wife and I choose everything together – including the grout colour – and we're both happier.

"Dust gets everywhere – no, really, everywhere."

I sealed the doorways with plastic. Dust still found its way into the bedrooms, the closets, even the kitchen drawers. Next time I'm sealing the entire floor and running air scrubbers 24/7.

"The cheapest tile looks cheap for a reason."

I saved $2/sq ft on bathroom tile. It chipped during installation. I bought more, it chipped again. Should have spent the extra money upfront.

"If a contractor says 'that's normal,' it's probably not normal."

My GC said a cracked foundation was "normal settling." I called an engineer. It wasn't. Trust your gut, not the guy who doesn't want to fix it.

"Never pay in full until the work is 100% done and inspected."

I paid a tiler 90% upfront. He left a week early and never came back for the touch‑ups. Now I hold 20% until I've walked the site with a fine‑tooth comb.

"The city inspector is not your enemy – they're your free quality checker."

I dreaded inspections. But every failed inspection caught something I'd have regretted later. They're on your side, even if it feels like a hassle.

"You will make at least one decision you regret – forgive yourself now."

I agonised over every choice. Then I made a mistake on the backsplash and realised it didn't matter. The house is still standing. I'm still alive. Let it go.

"The renovation will take twice as long and cost twice as much – accept it early."

Everyone told me this. I didn't believe them. Now I do. And I'm much calmer about the whole thing.

"The day you stop caring about the little things is the day you start enjoying the process."

I obsessed over outlet placement and grout lines for weeks. Then I realised no one would ever notice. Perfection is the enemy of done.
