Planning driveway sealing
Sealing needs a compatible product applied to a suitable clean surface. It does not repair movement or make a failing foundation sound.
Confirm coat coverage, drying conditions, preparation and whether the quoted price includes more than one coat.
Measuring the work for this calculator
Use the physical surface area and the number of separately priced coats. The model multiplies the coating rate by the number of coats, while any initial cleaning or joint re-sanding is counted once. Do not add a second coat charge if your contractor’s rate already includes it.
What the driveway sealing estimate covers
The calculator applies the selected work rate to the relevant measured quantity and shows each optional item separately. Small jobs may be affected by a minimum visit charge. Specialist preparation, failed supporting layers and unusual disposal requirements should be confirmed in the written scope.
The first guide option is general driveway sealing, one coat. Its allowance is £5–£8 for the relevant unit shown in the result. This is a published-guide starting point; it is not a price offered by a contractor on this website.
Choose the specification and separate allowances
The available work options are general driveway sealing, one coat; block paving sealing, one coat; tarmac sealing, one coat. Select the one that matches the proposed scope before comparing the result.
The project controls include:
- Number of separately priced coats.
- Add a separate initial clean (£3–£6 per m²).
- Re-sand conventional block paving (£1.50–£2.50 per m²).
Reading the budget breakdown
The results show the measured quantity, the selected work allowance and any separately selected items. A volume, unit count or coverage result is a quantity check, not a construction design. Where the model uses a minimum visit allowance or whole bags, the displayed total will not fall in direct proportion to a very small area.
Use the optional contingency to make a separate budget provision. Add a quoted fixed allowance only for work outside the model’s stated scope. Check the VAT basis before selecting the VAT adjustment.
Compare quotations for driveway sealing
Give contractors the same measurements and work description. Ask them to identify the main work, preparation, disposal, access requirements, drainage and any making-good that applies to this project. An apparent saving can simply mean that a different part of the scope has been priced.
Confirm coat coverage, drying conditions, preparation and whether the quoted price includes more than one coat. Keep the agreed specification with the quote, including any exclusions and the way changes discovered during the work will be authorised.
